I would like to see chicken debuff replaced with downshifted level cap on lower tiers. For example, player with lvl 32 stay as 32 in T4, become 30 in T3, 20 in T2 and 10 in T1. From one hand such approach will (at least partially) solve problem with depopulation of lower tiers, from other - will make purple rvr items actual for entire gameplay.
There are few difficulties - first of all it is hard to say what will be with mastery tree, may be it worth to keep separate profile for each tier.
Have my own interest - in original game i loved elven t3 and disliked t4 at all but had not a way to stay in my favorite area

Sorry for poor english - it not my native language
