Nope. The bad guilds do that, because good guilds run by good people realize the worth that a player brings and the non-DPS meter things hybrids bring. Even bleeding edge guilds realize this, but to them it’s not worth the trade offs; it’s not optimal (so they won’t take hybrid DPS), but that doesn’t mean that the hybrid DPS aren’t viable.
A big part of the bias against Ret (and Hunters, and Warlocks, and Druids…) is because of people remembering early on Vanilla and these tropes sticking with them. Huntards rolling on everything, breaking CC, having pets with growl on, etc. Does that mean all hunters are awful players? No, it just means that there are some who still had to learn the game (hunters, in general, improved markedly over the lifespan of Vanilla). The same can be said of Druids and, especially, Paladins.
Early on you had too many cowboys playing Ret that never even bothered to buff or heal themselves, let alone others. People grouped with them get a bad taste for “LOLRET”, and it builds as it happens over and over again. That doesn’t mean the class was terrible but that a lot of people playing it were garbage. Hence, the stereotypes and the player base aversion to them.
Then there are talent changes and skill changes/tuning that happened that people always seem to forget about too (looking more at Druids here) that improved the class past it’s “lolhybrids suck” first half or so of Vanilla. People still think Enhance is a great PvP spec because of mid-Vanilla WF triple crits. Those don’t happen in 1.12 because WF had been nerfed by then and people learned how to play around Enhance.
No that’s the strawman that you’re arguing against and, shocker, no class whatsoever will get, and keep, a raid slot with “impunity”. People don’t keep bad healers just because they are healers or bad tanks just because they are tanks. They replace them with someone worth a damn, just like what will happen to terrible Rets who tunnel vision and don’t buff properly or provide any of the support the class offers.
The only one lying to people is you and the others like you saying that Ret is a smoking dumpster fire. It’s not and, while it’s not going to get you top DPS, it is perfectly functional and can be a valuable member of a guild and raid.
