I like what I'm seeing so far... just hope that the various 'bank' style stacking issues and limitations gets addressed.
But even more so would be the updates to existing content. The idea what ToEE got the update confused a lot of folks, seeing as how both Gianthold and Eveningstar are both older and definitely more in need.
However, a particularly selfish reasoning would be 'Planar Focus' items. The possibilities of a revamp on these.. honestly....? I would think several staff would be twitching and fidgeting for the chance to make some changes. Updatable, craftable, various types of (augment or gear spot) slottable, customizable to be part of virtually any of the other equipment sets that tend to lock out all others from the update because every set requires you to use an armor.. etc...
You've gotta admit.... the possibilities boggle...
