You don't actually care about stat checks. You just hate when fighters do it.
isn't it funny how the phrase never comes up in discussion for the myriad of mages, supports, tanks, assassins, and marksmen who it would be perfectly applicable to, but no matter how conditional a fighter's power-up may be, you'll gladly bend the definition of "stat check" to squeeze them in.
As far as stat checking goes, outside of the fighters who have 0 downtime or condition to their stat sticks
, fighters are arguably one of the more reasonable stat checks when they're balanced because they tend to have more specific conditions to their stats as well as shorter windows to act with them than ranged carries and enchanters -- both in the sense that their durations tend to be shorter and/or that they are melee and thus have a very small range to actually make use of said stats.
To clarify, there is no actual issue with stat checking or stat sticks as a concept. They are a necessary design for a multitude of reasons and the hatred against them is arbitrary and misguided. There are certainly stat sticks that are poorly implemented, and those do warrant change, but a stat check, on its own, is not offensive or "unfair."
