Wheee! Vision is buffed! Time to use it along IM40 to load up lots of red and blu... what you mean that unbuffed IM40 tanks two of buffed Vision's colours? Thrice-damned flattened progression curve for 3*s between level 200 and 300!
Vision's blue and yellow power need to put him in front for each match while the CDs are out for them to be any useful. In average I'm getting only 1-2 "heavy" matches out of my 5-turns CD, no matter who I pair him with.
Using it when there is no enemy special tiles on the board also lock him out of any offensive option since you can't fire his red. The damage per tile converted is also not enough to make this worth it, and it only get rids of 2 tiles, with the types of special tiles being restricted to either strike or protect on top of that. ...In any case, Light Disruption should target attack tiles as well.
Vision simply needs his blue countdown to increase his base match damage by a percentage, like how Ghost's passive works, rather than add damage after the match. His yellow countdown should behave like Colossus' yellow countdown.
There. Now vision is a top-tier 3-star without being overpowered. The developers can send my check by mail.
