Can someone give me an in-depth explanation why Summoner is arguably the worst DPS?

[Lyrica_Ashtine]

Summoners have to do during dots:

Ruin
Fester
Rouse
Spur
Enkindle
Shadow Flare,
Poison Pot
Bane
Micromanagement of pet (aoe) or contagion, movement of the pet ..., HP of the pet, constantly pressing obey if you change target
I might be missing a few things, but Summoner has plenty to do

Summoner should not be a support class since that is the Bard's job. All that Summoner needs is a small buff in potency (Fester must hit a lot harder) and an MP fix. No offence, though, but since you apparently don't realise what SMN actually have to do, your idea of support should already be dismissed

Right, so you've been overglorifying Summoner for the past couple of pages now. Don't make it sound like summoners have it exceptionally harder than other classes, even tanks.

Most of the things you've mentioned in there are on off GCD ability-tier that you only use once every one, two or even five minutes: Rouse (60s), Enkindle (300s). Or even very situational: Bane. The are a few things you are consistently doing as summoner: Monitoring your DoTs and monitoring the CDs. If we were to seperate them, everyone's job would suddenly look stupidly complicated:
Bards have
-5 buffs to monitor
-3 DoTs to monitor (includes flaming arrow)
-Straight arrow to maintain
-Procs to maintain
-2 off GCD abilities to use
-One of them requiring close range thus planning whether it's a good time to move in or not
-monitor healer MPs
-monitor their own MP
-Plan whether foe would be worth singing at that point or not
-calculate in their heads when they need to paeon early or not
-mind their positioning considering they're the most mobile and people expect them to move first
-monitor their TP & invigorate

Monks have:
-2 CDs to watch (3 if you include Perfect Balance outside openers)
-3 off GCD damage abilities (4 including mercy stroke)
-Whether they are allowed to stun or not
-keep their stacks up
-keep dragon kick up
-keep twin snakes up
-keep two dots up (even three for those fracture fanatics)
-plan positioning (flanks/back aren't always available, depending on content)
-monitor their TP & invigorate
-use mantra if it's useful anywhere

And the lists can keep going ooon and oooon and oooooon. But no class is nowhere as complicated as any list of any size can make it. With enough practice muscle memory, habits and bias kicks in. The same applies to summoner.

Now I'm not denying they are in dire need of a buff or are hard or easy to play. But they require something far more fundamental: Change pet interactions*. Summoners hardly do anything with their pets. Microing? Please. The amount of microing involves pressing a button on the pet bar once or twice every minute. Or even not at all if you're using the Ifrit-egi. Rouse and Spur? That has barely anything to do with micro-managing pets. It's basically giving them some steroids and you mind your own business again. It's on the same tier as Raging Strikes: Use it ASAP or save it for strategic moments. So what do I think they need: A class overhaul that actually makes them feel more of a pet-based class rather than a caster that comes with a pet that does it's own thing.

*Submitted a suggestion ticket a week or two ago about this. I still have a copy of it if anyone's interested in it's content.
