Some ideas:
1. Be nice if there was some form of a snare, perhaps limited to wardens and Brigands that would slow the movement speed of the target by 30%, granted then people could kite; But at least I wouldn't get into trouble for soloing the 3chevs. This would make using bows a thing, as the best existing snare is basically pointless, except in very few circumstances and a couple of exhaustively slow bosses.
2. The Warden damage shield should kick out damage based on tiered levels of the target character; Every 10 levels it should double, rather than the ridiculously low damage it does now, clearly the skill isn't meant to be used above level 25. At level 50 the damage shield should be at least 35 damage per hit, and with the right reagent even over 50. I know, tech team is thinking about soloing the level 50 raid boss again... that was fixed awhile ago. (adds).
3. There needs to be a way to upgrade the static item drops in the game, and it should be multiple tiers with a 30% or more failure rate; There should be modifiers to both succeed and fail the combines with multiple chances to upgrade in different ways: For example, Hoggits legacy bracer (which the devs hate, I know), upgrade 1 could add one of the options (+1 armor, +1 run speed, +10 hit points, +1penetration, +10 ember maximum, etc... etc.. ). Just think of how many legacy and new items will be cycled out of the game due to these upgraded, failures.

b. Doing an upgrade should make it no drop too.
4. There is still a problem with the angle of attack versus the mob dictating the roll of the dice for base damage value. (This is a major problem, I'd think you want this fixed before it goes live on Steam).
a. You ask how a level 50 warden solo's a level 50 3 chev bear (or the raid boss), its because the right facing is max damage every hit (through evidently non-existant armor) and it has to die in 9 hits (wardens are flimsy). This is an ongoing issue. Flex looked into it, but testing was spotty and its still not fixed. The downside is that its much easier to do the minimum damage every hit than max, the window is 1.1 degree's of turn for max damage. Nothing worse than whipping out your state of the art "Best weapon in the game" and hitting for 22 damage (less than the slated minimum damage by armor) over and over.
b. A maximum damage hit does more damage to the mob that any armound of positional or penetration bonus, sometimes you have to fight from the front because the positional bonus is anemic next to max damage. PS for you overachievers, this is over 640 dps; I know right, total game breaker, aaand I'm not telling how much I actually do.

c. Before you get mad at me, remember I reported this issue almost 2 years ago.
5. There should be something else to spend gold on... guild perks which have to be renewed every 30 days would do it.
a. 1000 gold per month for an expanded guild bank limited to the guild owner, for example.
b. 500 gold per month for a flat "good will" from the merchants, -10% costs.
c. 500 gold per month for a Guild talbard (all guild members automatically get a fuzzy chicken on their chests in guild colors or whatever).
Or something like that.
