You simply can't skip building a Catalyst item early, cuz otherwise you won't have enough health to stay in battle, or enough mana to sustain W.

RoA is good only when you already snowball pretty hard. It is normally too slow to ramp up.

Mark gives minimal damage early on and MR which is somewhat irrelevant even vs a mage (as you will spend more time roaming around rather than stay in mid and try to win lane).

Therefore, GLP is often rushed as it gives instant power, sustain, tankiness and even a bit of utility. And no, you buy it vs anything, not just mobile champions.
