Based on my experiences and of course anecdotal experiences at that, other players, from what I've seen on my server Shiva, seem to be overly suspicious or just downright rude to players using regular classes, despite what their performance in-game or what their gear might be like.
I like to use Arcanist more than Summoner because it reminds me of the Summon versatility that XI had, you could have several summoners all doing different things and using different Avatars at one, which made for some interesting fights if anyone did the Trial By quests for them. So I like to have that extra action use and better availability for this class, since Summoner in XIV now to me feels slow and heavy, as if I have a 5% Slow effect on me or something while I'm casting for whatever reason.
Since I've started to lean back towards Arcanist use, for nearly all dungeons and Raids, besides Coil because some of those can be DPS check and to avoid unwarranted aggression and problems I'll often use Summoner, but otherwise I use Arcanist more than anything else. Just earlier I joined a Crystal Tower run, in-session because I only need a drop from Acheron, and after finishing the Vassago section leading up to King Behemoth, I was removed from the session without any warnings whatsoever. Being booted from the game without being AFK, Offline, Harassing someone, or Cheating is an illegitimate dismissal, and it honestly irritates me when I had done nothing wrong in the fight and was kicked suddenly for no reason, and the other 7 players deemed that it was acceptable to do it.
Has anyone else actually done some testing and experiments with Classes to discover that they're not "unusable"? Because some of them can be used without the Job, which is why Square Enix themselves admitted that this "higher-stats and exclusive gear for Jobs" setup was a mistake, because it imbalances and caters to Jobs and makes it seem like Classes are all but useless, when for myself, I can do more DoT damage with my damage over times, have better survivability, and still decent stats for the class when only 3 of them really count.
I plan on replying as seriously as possible for this so I hope I get better replies than I have in-game.
For the record now, I am not continually bumping this thread, others are. You reply with something besides the usual "OP needs to leave forums 4ever argument" and I'll reply to it, this thread dies when people stop commenting on it.
