Those who use TD are those who do not know how to run from a trans.
TS.
Best of 3 in my opinion.
TA is average, not good, not bad, but in most cases, you're trying to RUN from a trans in PvP.
TD is just plain for people who suck.
TS allows you to run from your opponent in trans, then trans without them ruining your trans and fight them back.
