How you arm your guys, which skills they have, what enchantments their items have, etc all have a huge impact your raiders performance. You can also actively manage a raid or level, especially with the hotkey bar and drastically up the performance of your raiders
Give us the option of visiting places, even if we can't "Activate" them like the Arena (I clicked a Yellow Exclamation mark and was taken out of the Arena before I could take my loot. There should be a dialogue asking if you want to "Go there now" whenever you click the yellow exclamation marks.
This game needs a way to very quickly adjust the auto-sell level. It's less of a problem early on, but when you get to the stage where you aren't interested in anything under level 300, every time you open up the game it becomes a hideous chore.
Basic explanation of combining:
When combining items, different stats behave differently. Attack, attack speed, lifesteal and movespeed stack additively. Crit damage stacks partially additively. (You'll retain most of the crit damage when you have a 0+X combo, and 2 items with 12 CritDmg will give you 19 CritDmg or thereabouts). Crit chance is the average of the two items being combined. Heal effects are cancelling in favour of the inferior one (i.e., 2 healing staffs will combine to give you the healing effects of the inferior one). Peculiar effects such as taunt, phoenix, guzzle will be retained fully.
HELLWRATH can be obtained by combining two Gods Wrath Axes. In addition to having high damage (Gods Wraths have the highest damage per lv of any item in the game), the resulting item will also have 999% Crit Damage and -200% lifesteal.
Regen enchantments are OP as all hell. With a little MP Regen and Transmutation, everything becomes an artifact. Never die because HP regens so much. GG. Still, heaps of fun and my productivity has been nixxed.
