Are u counting 1,2,3,4,5,6 and 7 hit? Every 7th hit have to be ideally a double han tap with basic, a datcha hit (followed by han/cls asisting) or CLS special to remove full TM
The best option is to try o make han hit every 7th hit with double chance to remove TM (double chance to dont get resisted), second best datcha, third CLS special xD
I run Datcha (only G7 without even mods xD), CLS 240 speed, han 210 speed or so...
To make urself a idea my datcha dont even die most of the times... So GG dont take more than 1-2 turns and seems i have similar mods than u xD
Just try to use both han specials to make sure either han or datcha makes the 7th hit, if u are in the 5th hit then use han special (the stun one) as 6th hit and then double tap as 7th (ful GG TM) and 1st hit for the next round.
If everyone but han have almost 0 TM (and GG less than 50-70%) then use han buff to let datcha and CLS get TM.
I find it so easy to solo... Single problem is my guild roster is so low and i have to clean P1 and then a bit of P2 and full P3/P4 so i need CLS for mi second team... To Solo P1 takes 15-20min for me, but i have to restart if i cant get CLS out at the end of the fight (or the start of the second) to use him latter xD
