They’re much easier to get through various avenues and measurably weaker than what comes later —
While costumes can help — they are more of a temp power bump than solve
If you start late — you are at a disadvantage because they’re is no trade off with regards to power.
They simply can’t be balanced without creating a stale experience — 4/80 is already the new 3/70 or 4/70
lower mat costs — 4 epic instead of 6, 3 rare instead of 4, 1 tome or mat instead of both
lower resource cost — bump feeder xp by 25%
This would put season 1 4/80 heroes cost inline with their power (above 4* but below for balance purposes are true 5* and 6* heroes)
It would give folks a trade off value to go ahead and level what they have — and are most likely to get — so they can get to the 30+ heroes for modern war and events despite having started — at this point — up to 3 seasons behind the longest term players
It seems a more palatable compromise to refunding mats through reset tokens, retiring heroes, creating 6* heroes or increasing team cost for strong heroes
it is scalable … something that’s clearly becoming an issue as more heroes are created.
