Suggested Sion buff:

Allow his Q's charge time scale down with attack speed. Not a whole bunch (Don't need a 2.25 second stun for a 1 second charge or anything), but enough that he can remain useful come late game. Because I find that Sion's power is very 'set'. His attack speed is locked when in his passive, his ult movement speed is capped at 950 regardless of what your items are, etc. I understand this is so that he can be balanced more easily, but it feels like Sion doesn't actually get much power from items because his stats are all capped. I think letting his Q charge time scale down as the game drags on would allow him to remain relevant beyond the early game when mobility is harder to come by, allowing him to actually get some damage/cc off.
