How far in is it still worth it to restart to get Kael?
I'm 2 weeks into daily logins with 3 epics and 7 champions at 4 stars + 40 including Elhain, Shieldguard, Warmaiden, graybeard, valerie, Saurus, Arminger and diabolist.
I've spent a decent amount of time grinding/farming for xp and silver, have most of the gear for Elhain close to maxed out (lifesteal).
So I'm wondering, with some people talking about restarting to start with Kael, how far in the game is it still worth it to restart to get him or is it more worth it to just keep on going with where I'm at?
EDIT: Also have Ogryn and then some weaker rares(and likely ones I'll use to upgrade other heros). Also have been doing the dailies since day 2 or 3 or so.
