Sarah delays. she doesn't USUALLY warp or LAG. but she always delays. Delay is legal and its better not to complain about things you can't change. At the same time, iclassic doesn't have enough staff looking into cheaters. Not saying sarah is a cheater. but its normal to be suspicious about her delay if somebody who is 80k-10k can do it using the simple C sparring techniques on the wall that she uses.
With all this said if sarah didn't delay
- she would still be a good sparrer
-probably wouldn't have the same amazing ratio/wins amount
-would still be considered a great idevice sparrer because she would adapt to not lagging.
but considering she's the only sparring using C style spar techniques that can get 80k wins and can beat advanced offensively/smart sparers who use far more advanced techniques... its normal to be suspicious especially because the iclassic staff don't do a good enough job monitoring sparers.
