Finding the game fun and engaging as usual but also underwhelming, it is just too damn easy, almost all challengers use hopelessly bad strategy and the only challenge comes from Sky Battles, due to the fact that they always have Emolga, an electric pokemon that can fly (and thus has a big advantage over my 2 flying pokemon).
All the gym leaders just fell flat on their faces, in previous games I usually remember them having atleast 1 exceptionally strong pokemon on their team or something with a brutal tactic (Milktank and it's Rollout ability in Gold comes to mind) but in Pokemon Y every leader has been a complete walkover so far.
Added into that is the EXPShare, in old games it was a useful item but in Y it is just an overpowered super leveling tool that before you know it from just doing the basic battles you're way overleveling the content. In the old games it was the opposite in that you had to do extra fights and training to keep up with content.
I've turned off expshare now, but yeah I'm finding the game too easy at the moment, I've solo'd gym leaders when they have a type advantage mostly due to poor use of abilities on their part, and though I have a team of 6 I've never come close to needing to use them.
