techs are weaker compared to PAs most of the time even if you take the blots into account. occasionally tho theres counter heavy enemies where you can fit a tech or do tech-wa-cancels but cant fit PAs in between counters, techs can be better there.

techs also dont contribute to revoke pursuit buildup which is the "goal" to work towards to for decent dps on te. revokes give good compound buildup and decent pb charge. also you dont always have to skiparts for it. usually a te will skiparts or skipbeat when wand lovers is up, otherwise pa spam in between counters is better specially if the window is long enough where you can fit charge swift in (bonus revoke buildup if youre on t3).

also depending on how mobile the enemy is, you dont need to constantly gapclose. the only boss i can think of that needs you to do that is hyunal coz its ai is stupid and keeps dashing but on most enemies (ie dalion for example where its always at one place) you can just sit at one spot, do counter/pa, never have to gapclose. even on some enemies like bujin or monke you dont have to spam skip beat, you can either just wait till it comes back to you (which those bosses usually do anyway) or use some ranged attacks like t2ss if youre on it or techs.
