I would undo PvP xp ASAP ---> Possibly the BIGGEST mistake SOE has made. Its decreased server populations on PvP despite what a few ardent PvErs who post here (inch wincy spider....) claim
I leveled to tier 8 -->
- Essentially its constant ganking and griefing. If a x2 raid can kill a lvl 72 8 times in 5 mins they will (unlike the t2-4 lock teams who would at least wait until u were off recent
). Its rare to see a good even group fight.... - UNLIKE T2-T4 locked teams there are no "bigger fish" Orange cons to keep a lvl 80 in line.
- The lower tiers are relatively deserted now, i haven't seen a good x4 vs x4 in ant/cl in months!!
- Many guilds and friends left after their playstyle was ruined by this change and i highly doubt EQ2 will get 100s of new players with the next generation MMORPGs on the horizon.
@ T2-T4 before the "NGE/CU" 
- A casual player with a family/job etc could join friends of similar lvl to him/her and enjoy active group vs group pvp. We new our enemies and sought out the deadiler groups.
- There was far less griefing than T8
- The servers had healthy populations (well other than Vox --- its SE though).
- New toons got help from active lower tier players and crafters, need that HQ finished?? need Anguis killed?? no problem
NORMALLY if a company changes something and realises its messed up they undo it!!! Don't NGE EQ2!! I've no doubt there will be a few who will disagree with me....but then again there are some who think SWG is still a TOP MMORPG
