Looks like it didn't take long to see what the clear "winning" set-up is. Was playing a match there in wt against a guy with over 80 power, 90 something serve and had the berserk server trait. I was using my ultra-defensive baseliner with 82 speed and high stamina, with the diesel return trait. I thought it would be a very interesting match to see how the different playing styles work against each other.
Well it didn't take long before the match was pure snoozeville

The berserk serve is just too much. I mean you don't even have time to react or get into position to return..it just booms down way too quickly. I managed to guess a few times and get tha ball back but it was still an easy 1-2 punch winner for him.
I think for the itst tour that berserk server trait should be considered carefully but that is just my opinion. Maybe others think it is perfectly fair
