Isendra is the Diablo 2 Sorceress, and the one who trained Li-Ming. Her role in the Nexus is that of "generic mage", much like ETC and Muradin are "generic tanks". That in mind, her range, CC duration, and burst damage are all generally lower than other mages. Jaina provides stronger, more reliable Slows and zone control. Kael'thas provides better hard CC, zone control, and burst damage. Chromie and Li-Ming out-range and out-burst Isendra every time.On the other hand, Isendra is much more durable, less mana hungry, and more flexible through talent choices to fill the niche the team ends up needing. As a "generic mage", she doesn't specialize into any element, and always has at least one fire, one ice, and one lightning ability.The one role in draft she does excel is her giant killer, with percent damage available on both a Basic Ability at 13 and a Heroic upgrade at 20.The hero fantasy is built to make you feel like you're playing Diablo - instead of enhancing your Basic Abilities with talents, you replace your spells with better ones as you level up. New ability icons, animations, sound effects, everything.
