I can confirm this, elementalist champions are far more difficult to do than they seem. My very first custom LoL champion was an elementalist, and the initial concept was all over the place, with way too many effects going on. Even now, after years of tweaking, reworking and updating, my champion's kit is still pretty complex and likely overloaded. I should probably get back to her...

I'll give Radya a more in-depth review, but for now I'll echo a bit of what GreenMoriyama said: the idea of an elementalist champion is rich with potential, and making that elementalist champion a combo mage makes perfect sense, but that also means the very first thing you need to watch out for is kit complexity. If your champion's going to have a lot of different effects, then those effects need to be themselves elemental, i.e. they need to do one specific, distinct thing, and nothing else. However, your champion has a ton of different actives, combos, on-hit effects, and even a pet. You're going to need to streamline this kit a lot, and probably remove a lot of features outright.
