The one suggestion I would love to see implemented (Sant's original idea) -
Keep a lore restriction to lvl up

IN other words..there should be a minimum lore target to reach the next stage of lvls every 10 lvls.
And this number shud go on increasing!
For eg at lvl 79 u shud have at least 50k lore (random number off the top of my head) before u can reach 80..
100k lore to hit 90 and so on.
It's the only way to make ppl do quests also rather than pure leech their way to 100.
