Ah Ra.. it is so nice when a simple kit is so good it never really falls out of style. I remember before ever playing smite i'd look up to see what people thought about Ra, mainly because i feared that smite players would be like the league players i keep hesring about. Ra was my mage main for a long time and i still like to pick him up every now and then, sometime it's just fun to have a simple gamepla.
You are nearly there...... You should try telling people to like and subscribe. You have a good amount of views compared to subs. Either draw in those viewers not subbed, or add likes from subs. A reminder honestly helps.
Same idea with those two just different playstyles really. On the whole Kukulkan has the benefit of a lot more zoning and better self peel so he tends to be better.
