Invoker is known as a character which no-one but the very best should use.

He was also singled out by Guinsoo for being really bad game design with too much burden of knowledge. (Granted Guinsoo was talking about the original Invoker which had 32 skills, however he said that the current one didn't get very much better)

Also Invoker currently has 10 skills (which he does Not get all at once, usually you'll miss out on leveling one of your elements until about level 10-11), Kiya has 12 skills in her first kit (and that's not including all the passives) and 9 in her alternate kit, and she gets them all as early as level 3-4.
