I liked it, but there is few things to balance out, firstly warrior runing away lose a lot of hif fighting potential, because bows attack all time he run like chicken without head (and no item making him to do that) and in that its better to give him ranged weapon than him being tank
Other things, small bar with show how long till skill can be used (necro ress etc)
Visible level of weapons and automatic sorting to highest lvl (small number in lower corner would be enough).
Healing ring change to 20% per 4 s not 200 hp its like nothing after few levels.
Some statistic would be nice like average damage dealt/taken in 2 mins time
More items and especially profession rings its great idea :D (like potion drinker ring: automatically gulp potion if lower than 20% hp) Mages staffs,debuffs etc etc more content for sure is only good thing.
Sometimes item with too long name don't show level
Space between level and number because L and 1 looks confusing so close to each other
Not everything levels up, not sure if intentional or not.
Overall fresh breath of idles, looking for some update :)
