More suggestions:
Bring back the Blizz-like feeling of spawn zones and spirit healers, at the very least add it for the arena so that players can't spawn behind you. Maybe a 30 second mass heal just like Battlegrounds would do the trick there.
Reduce the cost of honor gear, and make an upgrade set.
Make vote gear better than the newest set, or make it able to upgrade to a set that is 500 stats more than Illustrious.
Make the VIP Dungeon, Pythios, Skywall, Grubba and Zuljin a bit easier by 1/8th. Due to the lack of population and the lack of extreme donations, most players can't actually do anything with this content but die over and over.
>>An alternative solution would be to make the drops group loot (except Pythios, he just needs a bit less melee damage in exchange for 100m more life) for people that want to play with others.
From what I have done with my own characters, Grubba does not seem to drop his maul very often. 0 drops : 14 kills is the current running record I have for what he has dropped. I would like to see this looked into for a possible bug. I was told it was a 20% drop chance, but of course I could be very unlucky.
Farming materials in dungeons are perfectly balanced, but the mobs lack the feeling of a challenge. Add patrolling mobs as well as various ranged, healers, and casters to the mob mix. Change some of the layout of the mobs in lower dungeons and instances, as they seem stale; that or create a new set of dungeons which seems less likely.
))(( = Important to me pre-patch
))ADD SHIELDS to the transmogrification vendor please!((
))ADD Block rating to VIP shields, remove mastery completely to avoid Mastery Bugs((
))Make tanking and healing more of a requirement((
))Reduce non-healing class/specialization heals((
))Reduce Priest's bubble's by 1/3 or remove the secondary bubble when a critical heal occurs((
))Buff Death Knight's melee output by giving more Attack Power bonus via Strength((
Thanks for listening to my opinion. I will work out some more ideas for later.
