Cool story................................................................................................................................................. You should throw some more dots at it.
People discuss these very relevant issues because they're relevant, not because they're stupid, lazy, or impossible to satisfy. You appear to have a lack of understanding of the reality on the ground if you think MNKs are only good on training dummies, or that SMN is perfectly fine. Whatever you're OTing with Titan, it's not relevant content. Just for fun, let's go through:
1) People complaining about DRG: Yeah, because it was bad. MNK and NIN had way more survivability AND way more dps. No one wanted DRGs.
2) People complaining about MNKs: Yeah, because it was bad. MNKs and melee in general had low dps because they constantly had to run away, lose stacks, not keep combos up, etc.
3) People complaining about BLMs: Yeah, because it was bad. No one wanted BLMs because their single target dps was garbage. It's still pretty bad, to be honest with you.
4) People complaining about BRDs: Yeah, because it was bad. BRD can STILL top dps charts on some fights that have excessive movement, because they can attack always and forevers. Even though their single target potential is the lowest, they still put up impressive numbers, and that's before buffing the damage of the rest of the raid.
5) People complaining about SMNs: Yeah, because it IS bad. SMN is now the lowest single target dps in actual fights, and will never be anything else except in fights custom tailored to them (like Levi EX). BLMs are almost as bad. Casters need a look. They don't need to be competitive in dps with physical dps, but they shouldn't be as far back as they are. Especially when for example BLM is a "pure dps job" according to Yoshida. Uh, no. MNK is a pure dps job.
6) You can battle raise? Sure, at the cost of a huge chunk of mp, greatly lowering your dps in most fights. If people are dying so much you need to Raise, things are already going very wrong.
7) You can OT with Titan? On what? Relic quest Chimera? Relic quest Hydra? Titan won't tank anything worth talking about. He'll just die.
8) You have huge/constant AoE dps? Sure, if you're a BLM. You can Bane stuff for fairly large AoE, but a BLM will destroy you, and other jobs can compete with you on AoE with large packs, probably destroy you. SMN only shines when there are multiple, but few, targets - ones that will survive constant DoTs and Festers, essentially letting you single target dps more than one thing at a time.
9) SMNs are not for lazy people? No, they're not, but they also aren't compensated for the hoops you have to jump through to keep your dps at the ceiling.
10) BLM is boring? What does that even have to do with everything?
11) MNK is only best dps on training dummy? No, they are the best dps on almost everything. If MNK isn't top, then BRD is, because movement heavy fight.
