The engineer class is currently litle bit useless, so I suggest a huge tweak to it:

Instead of having some random redstone parts, I suggest that The engineer should spawn with

Blueprint Book

(with a texture of book and quil), that would have different

blueprints

just like the shop gui has.

The blueprints

would need certain resources before you can

"buy"

them from the

blueprint gui.

The resources would be everything from redstone and emeralds to planks and stone bricks.

The blueprint

will appear to your inventory and you can place it to the ground and wiev what kind the structure will look (like in wasted) but when you place the structure down you can't pick it up (unlike in wasted) , the structure would be normal blocks that can be destroyed with right tools.

The blueprints

would be anything from dispenser cannons to

obsidian machine

and some

blueprints

must be built first before you can build some other structures like

obsidian machine

would be reguired to get

obsidian

to some other

blueprints.

Edit:

I came up with some blueprints that could be intended:

Dispenser cannon: requires 4 dispenser, 16 redstone, 3 emerald, 8 stone brick and stack arrows. The arrows will be inside the dispencers (every dispencer has 16 arrows) when the structure is built.

Stone gate: requires 16 iron bars, 16 stone bricks, 48 redstone, 5 emeralds and 3 obsidian. The gate would have a lever that when turned on will lower the gate with same concept as building structures and if you break a iron bar from the gate it will not come back if the gate is closed and opened again. If the lever that opens the gate is broken the gate can't be opened/closed with "selfmade" lever. Pictures: requires 16 iron bars, 16 stone bricks, 48 redstone, 5 emeralds and 3 obsidian.

Obsidian machine: reguires 8 stone bricks, 10 emeralds, 64 redstone 2 buckets and blaze powder. It would be a structure with jack o'lantern working like furnace and it will turn cooked redstone block to obsidian block. It would have slower smelting time than normal furnace and the jack o'lantern would be destroyed if you try to pick it up (to prevent people from creating their very own irongolems).

Wooden gate: requires 16 fences, 16 logs, 28 redstone, 4 emeralds. Would work just like the stone gate but just a cheaper and weaker version.

Drawbridge: reguires 48 redstone, 6 emeralds, 28 stone bricks, 32 string, 5 obsidian and 3 redstone repeaters. It would work like the gates, but just vertically.

Detector: requires 1 emerald block, 8 redstone and 1 obsidian. It would be a small tower with redstone torch on it. The redstone torch will activate if there is player from enemy team within 3-5 blocks from the detector otherwise the torch is deactivated. This can be used to spot invisible enemies or set up efficient traps. Pictures: requires 1 emerald block, 8 redstone and 1 obsidian. It would be a small tower with redstone torch on it.

Buildable Brewing shop: requires 15 gold, 1 sign and 8 redstone. It would be a small tower with the brewing shop sign in it. Notice: it can be griefed by teammates.

Buildable weapon shop : requires 15 gold, 1 sign and 8 redstone. It would be just like buildable brewing shop, but just the weapon shop. Picture: : requires 15 gold, 1 sign and 8 redstone. It would be just like buildable brewing shop, but just the weapon shop. Picture: http://imgur.com/CsQfZEf

Placeable melonfarm: requires 4 melon blocks, 12 stone bricks and 4 emeralds. It would be a small melon farm that you can place where you want it. Useful to get melon supply to your mid- or skybridge base or perhaps make it easier to get food in amazon? Picture: requires 4 melon blocks, 12 stone bricks and 4 emeralds.

Dock: requires 64 planks, 16 redstone, 6 emeralds and 1 dispenser. It would be a dock with a chest and dispenser. The dispenser is activated when you step on a pressure plate above it. The chest will hold planks and everytime when the dispenser is activated it will take 5 planks from the chest and turn them into a boat that will be thrown out of the dispenser. Dock would have 10 seconds cooldown before you can spawn a new boat. Pictures: requires 64 planks, 16 redstone, 6 emeralds and 1 dispenser. It would be a dock with a chest and dispenser.

Forge: requires 1 anvil, 64 stonebricks, 16 iron bars, 64 redstone, 10 emeralds, 5 dispenser and 7 obsidian. It would be a sturcture with 5 dispensers, a chest and anvil. The chest will hold iron and there is a button (10 second cooldown) that will activate all the dispensers to drop 1 iron sword and full iron armour ( one gear from each dispenser), the materials to iron gears would be taken from the chest. The anvil can be used to break iron tools and armours to iron ingots by left clicking while holding iron item you want to break into ingots.

Iron furnace: requires 8 iron ingots, 1 emerald and 8 redstone. It would be a "normal" furnace with flame particles coming out of it (like the ender furnace has enderparticles). The iron furnace would be 2 times faster than regular furnace but also consumes fuel twice as fast. Picture: requires 8 iron ingots, 1 emerald and 8 redstone.

To prevent abusing this class I suggest that instead of having a no build range from nexus area, the blue prints wouldn't be able to build if part of the structure goes to worldguard area or then that part that goes to worldguard area won't appear at all.
