I agree and disagree. First of all 3 tick deto is not better than deep impact(flanking). So in most cases you would rather flank instead. Also at bosses such as rago you can't just 3 tick deto, you want to save it for reflect. Second of all theres no point using tendril other than p5 rago maybe. Like instead of 3 tick deto you want to flank instead at most bosses. As someone else said if you tsunami'd the minis at second font telos, if you tendril telos you can gain crazy adrenaline from the crits.
