All my main hero's ar at skill lvl 23 and i have a few max hero aids. Is it better to max out hero skills at this point or go for hero aids first?
Most of the good heroes are getting lower rage at level 30, ambrosia, toxic shaman, great sage, arcane caster.. I will recommend max out the skills for all your main heroes in priority, then mode on and max out aids.
Hero aids are arguably the strongest element in this game. Some need a really high hero level to become an effective hero aid. But once they do, there's no stopping the main hero.
In my opinion, this may differ to others, hero aids will mostly count for survivability. The main hero skills will be mainly for offensive or support purposes, depending on the hero.
I will edit this message later when I can send a hyperlink to the thread covering most hero aids to date.
