I think Irelia's gameplay patterns (passive, Q, E) offer a lot to the game, and their interactions with each other create a diver that actually has to work for their engage potential. The unique engage pattern she has when she doesn't have kill potential makes her a great champion as far as gameplay, in my opinion.
**However, her W and R are boring, uninspired abilities that simply make her kit about how well she can stat-check people and how well her kit can apply Trinity Force's stats. **
What I really don't like is how she scales so well with literally any stat that makes up Trinity Force outside of Mana Crystal, or a single relevant defensive component if in a non-favorable match-up->TF, and can proceed to roll over a good majority of match-ups,
>>>>>regardless of stun<<<<<, if anything is even slightly in her favor and they aren't building shit-loads of HP early on.
