I like that they're honing in on the "dashing in and out of combat" mage style. Though I still wish they had made the movespeed scale with either the Q level, or with ult level. Oh well.
Overall I still like her as a champ and think she's very strong.
This right here^
If you're not enjoying it, don't play. Spend your time doing something you find fun or enjoy rather than doing something you're dreading or anxious about. I took a break in Season 3 as well (i think....time flies) for 3 months or so because I wasn't enjoying it, but I've been playing semi-consistently ever since.
The only reason I play is because I want to. I like the champions, like the flow of the game. There are still days where I don't feel like playing League, so you know what I do? I play games on Steam, or I read a book or find some other activity to do.
Without getting crazy serious - Life is unexpected. Who knows what will happen tomorrow, so enjoy your time doing things you want to be doing whilst you're still around.
