I have been impressed with the direction LOTRO has taken since the new Executive Producer, Severlin, has taken the reins:

A new raid

Performance improvements for many

Open communication via Cordovan with the community

Seeking feedback from the community on the direction it would like to see LOTRO go

U18 and 19 were both very well done from a content perspective

Epic storylines have been fantastic

Premium housing

And today they dropped that Bullroarer will be open to test out performance upgrades and creep love:

Fellowship/Raid performance improvements:

Target effect updates have been streamlined. We hope that groups will notice a performance improvement, especially a reduction in client hitches when first targeting a mob or player with many effects on them.

The clean up of effect information when a target is defeated has been streamlined. We hope that players will notice better performance in cases where many mobs are defeated, or when a boss with many effects is defeated.

Our particle effect system has been updated to hopefully make better use of information caching. We hope that players will notice better effect display performance over time during a play session.

Monster Play Creep adjustments:

Increased Mastery Corruption values by 12.5%.

Mitigation Corruption values increased by 30%.

Critical Defence Corruption values increased by 15%.

Resistance corruption values increased by 10%.

Critical rating corruption values increased by 10%.

Damage and healing values increased by roughly 15%.

Max Morale base values have been slightly increased.
