Disclaimer: I have all the 3 
and half of the 4
fully covered and the other half (up to 
) is at least halfway there. So I’m in a good position to hit that 1300 mark every PvP, get the legendary token every time it comes up in DDQ, and (aside from whales) be part of the first batch of players to have multiple decently covered 5
characters.
I understand that they are very hard to get and long term goals, but in a few months, players are going to have multiple of them covered. And with such a HUGE power gap between 4
and 5
, we’re in real danger of going back to the 4hor/XF days where that is literally all you see after crossing a certain threshold of points. I neither want to be pigeonholed into using SS/Thanos or whoever every PvP or go up against it all the time. It would be more interesting to have to face SS/4hor, SS/DP, Thanos/PX, Thanos/JG, etc..
By limiting teams to having at most one 5
, instead of having a choice of one or two other 5
characters to add to the team, players would choose from 20+ 4
. The 5
s would still feel epic, and having more than one of them gives a player the advantage of choosing which one is best for a particular event, but it wouldn’t completely invalidate every character released so far.
