Is our sub fee not enought

Will still need a rewrite. 2.0-4.0 is a whole story, not a collection of short stories with not much connection between them.
Or we will get a chronology fragmented story like in FF XIII-2, where you start with fighting for Ala Migho, and then enter your first time Eorzea, following with a raid to the garlean capitol, and at the end to fight against Nidhogg.

I take it you don't really know how GW2 manages story. Or... any other MMO. If you want the whole story, you play through the quests, but starting the new expansion should NOT require having completed the past ones. It doesn't require jumbling up the story at all. You are just able to pick up the expac's starting quest at your liesure (so long as one is of the appropriate level).

This is kind of a side topic, but the jump potions are just another symptom of wanting to simply use the mogstation as an easy, cash-grabbing out.

No, they are a necessity brought about by having multiple expansions and the level cap raising. Nearly every major MMO in existence (and most minor ones) have a level skip option after a few level cap raises.
