As the cap increases, the value of being an iconic relative to just being a sorc has gone down, and the complaints about melee being in a bad place due to leveling differential, ranged being in a bad place due to same, even warlocks (lolz?) being in a bad place relative to a sorc keeps going up. Part of that differential is that Sorc does have to level from 1, or pay for a +1 heart to capstone, so Sorc has to level much faster than a melee which can 18/1/1 an iconic at start at 15. We could shrink some of that differential if all those iconics also had to level up starting closer to the Sorc at 1 on subsequent lives.
The value of being an iconic is the same it ever was.
You start off 5 levels away from being Epic.
That has never changed.
The amount of time actually spent in epics is the same for both, no matter how much the cap increases.
