1. First of all, it isn’t only my way of playing the game. The devs of the game clearly don’t want players to use these tools especially in PvE, because they create an unfair advantage. So if somebody clears an Ultimate with these tools and apparently thanks to these tools, they have not cleared the content as intended by the devs. In a sense they’ve cleared something else.
2. Most of the time, what wipes parties in FF is not DPS checks, it is incorrectly solved mechanics or standing in an AoE. Therefore using DPS meters brings no value to the fight. Regarding other tools, like zoom hacks and mechanics solvers / announcements, I stand by my claim that people who need them, are not playing the content as intended and are missing the entire point of high-end content in FF14. Which again, is not about DPS, but about solving mechanics.
