I understand what you wanted to say , but I see here 2 different problems.
1. Building bonuses are not easy to get for newl players because when they join big old clan , they must fill soulwell at first. So I think game have some protection.
2. Main reason why we have some characters with anabolic
abilities and skills is their way of playing. Exactly like you said some half-living accounts are playing only during specific event or Champhionship with maybe added DG fights because DG fights gives best SE/XP ratio. But that is their choice. They choosed slow but very strong development of their character. I think they cannot be punished for that. What is sad is game is not trying to support active playing. You will get minimal guaranted SE from 99.9% of your duels because 99.9% accounts of low level are dead and SE-empty. So you can choose 2 ways : active playing and not be able compete in Champs or slow playing with gaining advantage from game rules. Unfortunately on low levels using AS for gear is waste of money, as active player you have not any chance to those "zombies" even if you spent dozens euros monthly because lack of "SE full" targets.
Anyway bonus points to abilities from Champ medals are less and less important as you will go higher as those bonus points are making less and less in % from total. Also when you have more than 10medals, you needs more than 1 medal for +1 bonus in abilities.
Also look at last addition to game - Fetish. It is clear this addition is for very ACTIVE players and also many from fetishes will be better achievable for premium players - here is area where you can invest your AS more efectively. And look at bonuses which Minion can bring to your character - much more important than Champ medals.
Especially when you know we will have many Minions and bonus will be cumulative.
