hessah was pretty right, atleast the first 3, they should be the way u had it as lvl 3
because item pick up works good, but u will use tab to attack more because the item pick up gets u the closest item, not the 1 u want.
so u want 1 and tab to be close...and heal is important, but i wouldnt make it so weird to make it like attack, heal, collect because it's just dumb
and to me spamming 3 works nice
