is not because they are stupid, is because someone thinks that balancing one hundred and forty nine "unique" characters for one map is easier and better, while updating and changing things one that map every 6 months.
it get's funny because with 3 or 4 maps design would be possible to balance the game in a funny way however, everybody hates waiting... so maybe no one wants new maps?!
hum... Since increase of resource may result in the wrong idea and increase, not decrease of the problems...
I suggest we do a Thanos snap. boom, I wonder what champions I like will be gone.
well, that is if you aren't okay with the champions.
if you problem is the mechanics in the map, let's ask for a new one.
P.S.: trust me, the Thanos snap will lead to some temporary imbalance, if done randomly and impartially, but will lead to a more balanced game in the future, in fact some CCG due exactly that to balance they game.
it also make sure that the current "mooar champions" philosophy stay in place.
