With proper boost allocation, you can max out your acceleration and all other important stat categories on the Athleticism side by Legend 2. Balance and Durability are utterly useless along with some other major categories.
So everyone can just end that argument right there in regards to acceleration as long as your a Legend 2.
Shot power wont matter that much against human goalies in 6's games, which is where EASHL really thrives.
Grinder is by far the best build when it comes to being a winger imo. I'm a legend 3 now and I absolutely love my build. One of the fastest players on the ice but I can still crush just about everyone with big hits (except big goon dmen). I'm a legend 3 right now but the same principles pretty much apply for any decent card level. I can post later if anyone is interested.
Now, I think I'm starting to feel a slight drop in offensive attributes. Maybe it's just a string of bad games for me, but I feel like I'm having more trouble making and receiving passes lately.
Gonna put my stats back to the way they were and see if anything changes or if it's just all in my head.
Edit: One thing I can be 100% sure of is OA has minimal, if any, effect on deking. Loose puck dekes are easier (or at the very least, equally easy) with DK at 90 and OA at 65 than with DK at 85 and OA at 90(+).
