How do people calling themselves casual feel about the difficulty level?

Oh i will say what i have done in game like everyone here.

So i have my main a PLD full 90 alagan so my warrior indeed.
My dragoon ilvl 90 too !
My BLM ilvl 86 (mix allagan with ct)
My monk ilvl 84
My SCH who are ilvl 76

Well not that bad, i play till the release on moogle server, i have done so much primal extrem, i done bahamuth everytime, now if you think all of this is too much, i will tell you, when 2.2 is out, you can stuff all class in ilvl 90 in one week. Thing i have done in 6 month ?

Tell me again when you have beaten T5 for the first time ? 1 month ago you were struggling for P2 there. So ok, *maybe* you downed it for 4 weeks now, but still, it took you 6 month. There will be the same step of difficulty for T6-9, prepare for an other 6 month period with a lot of things to do.
edit : nope haven't beaten yet. You aren't out of content

When I see people say things like this, I want them to solve this problem:

gaaah MUST.NOT.RESOLVE... Was too much trouble when I was studying equations, they were everywhere, and so damn boring with sinh(ln(x^4)) all over the place just becaus emy math teacher loved that and loved to destroy any hope in us.. (but yeah this one is easy once you know how equations work)
