Maybe someone can help me with this.
Which is "better"a high level hero as Aid with high skill level and bad skill Aid (Pounder for example), or a lower levelled Hero Aid with lower Aid skill level but good skill aid(for example Berserker).
When i ad a high levelled hero as Aid the '"Aid result" is much higher (HP, ATK or HP/ATK %) or is it better to have a lower levelled hero with a higher skill level which gives a better Aid result?
Better to focus on long term as game is a marathon. Do not put any resources in pounder and other old less useful heroes.
But to answer your original question, it depends....
Best thing is to put resources in heroes with staying power that will be around a while. Abyss, Toxic, Wolf, Rath, Wonton, Amber, Pan etc.... Some heroes are much more important than others, part of the game is figuring that out!
Try to keep the average hero level high. Maybe you can have a lower hero level as aid (like berserker) but keep the other ones at high level.
It is important to figure out a balanced layout since you actually need stats but also good aid skills
