At what point does drago overtake elric as the. Better tank. I have read that drago doesnt come into his own until about 80, but at 45 both 3* and blue +2 drago only has 500hp less than elric. But draho does have higher magical and physical armor.

You'll need both for epic arena and guild war so work on both

I´d go for Drago and Leon

From what i remember they depend too much on itemization ,drago keeps getting good or bad till lvl 80 while elric doesnt (tanks at early game are awful and doesnt completly do the job in arena).
