Please consider implementing the following QoL updates, which I believe many people will enjoy and should not significantly affect the WotLK experience, for example:
- Add a third or a third and a fourth talent tree. Such classes like druid or paladin would benefit a lot from having pre-saved trees for different specs, it can be expensive in gold to support the in-game economy.
- Add aoe looting. It is just convenient to be able to one-click loot from all killed mobs.
- Expand stacking mechanics for items. For example, priest buffing reagents stack up to 20 per bag slot, and if I want to buy reagents for a week of gameplay it takes from 5 to 10 slots just for them. The same with warlock soul shards etc.
