Issis

Isis is more of a support mage than Chang'E to be honest. Spirit Ball is a ranged stun. You should be using that to peel for other members of your team, or to set up kills that you may not necessarily get. Her 3 and 4 both set up as well. Chang has very consistent damage on two of her skills (three for this horrible period of time between last patch and when she gets nerfed next patch.) Just because she has a heal doesn't make her a support. You need to burn Chang'E down fast in team fights because she does so much damage in addition to her utility.

Isis doesn't need to be getting kills to be useful for the team. You should be adding a good amount of damage and not dying 'too' much, but flat kills isn't a good judgement.

And lol at Chang'E not being OP right now. She needs completely camped and sat on in the solo lane otherwise it's GG. She was always a dangerous threat late game because of how she scales. If she builds breastplate and void stone (which every Chang'E who isn't terrible will,) you can't burst her like other squishies because of her low cooldown aegis/mobility/heal/protections/ult. What you end up with is a character hitting your whole team for 400 damage every 3 seconds while buffing protections and healing the rest of their team. Add in her ult which is possibly the best team fight turner (it's her or Zeus,) and you have a broken character.

She was held back earlier by a bad early game lane clear that led to her falling behind (and she's bad when she falls behind,) but not anymore. Now she can push early game and get ahead. She has no weakness outside of being somewhat easy to gank. That's not a real weakness in solo queue.

I didn't list her with the other OP gods because I'm relatively certain that she's being nerfed soon. Zeus, Agni and He Bo on the other hand seem to be HiRez favorites. They escape the nerf police every Wednesday. She'll always be easy to play with her 'skill'shots though, so she's a good beginner god. I'd just prefer if the easiest to play gods weren't the strongest as well.
