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

There isnt anything inherently wrong with SMN. The ppl complaining about the job, just want to see SMN being top DPS because they MAIN it.

I'm a BLM main; I'm completely fine with it being stronger. The gap is too big, though.

To make matters even more laughable is how half of the ppl complaining about SMN, have already beaten T13 as a SMN.

It's crazy, right? It's almost like having to deal with the job's shortcomings somehow made us even more aware of them... A great BLM had no issue getting through T9 before the buff; a great DRG had no issue beating T13 before the buff. That doesn't mean the jobs were without issue.

Both jobs have full motion of freedom, making them virtually immune to all mechanics except raid wide AOE while having birds eye point of view across the arena.

SMN's movement is just as limited as BLM in Final Coil. BLM can move freely during procs, SMN during Bio; both can Swiftcast once a minute. Ruin II will keep up DPS at that moment, but will leave a SMN crippled later on. It's like Scathe in that, yeah, you could use it during movement, but it hurts more than helps.

A BRD could literally stack CRIT all the way up to the 700, which is the same as 50% crit.

That's more around 30%.

Its not like there aint other options around like I dont know...ARACHNE, several which are BiS anyway.

Yeah, it's not like you'll need that HP from higher item level gear to survive basic mechanics in T13 or anything...

You can't call BLM support when 2 of the 3 abilities you list are cross-class from Arcanist. A more reasonable statement would be Apocatastasis, Lethargy, and Sleep. Two of which don't work on most 8-man content (Lethargy works on Scylla and I think Glasya, but that's all that I know of).

Apoc is the big advantage over SMN. Preventing a death is generally much more helpful than a Raise that would cripple the caster.
