Ahri's Q Speed Boost
With the removal of DFG and, to a certain extent, changing Ahri from an Assassin to a Kite Mage, I feel it was nescessary to give her this Q move speed, absolutely 100%. I see exactly why they gave it to her, so she still has good mobility outside of her ult. I just feel like they could have done a little more for this mechanic, added a little more depth in my opinion.
I think a good change to her Q would be to have a speed boost on champion, large jungle creep, or epic monster hit, and maybe like half speed when it hits a minion or something. I just feel like the free speed boost kinda sucks, on top of her ulti too.
What do you guys think?
