OP, I think I was around level 28 or so before I understood what Transpose did and thus how to THM/BLM effectively. Before that, I was an Ice Mage because I could always cast Ice. Whenever I used fire, ran out of MP and had to wait for it to regenerate, at which point Astral Fire would wear off and I would have start all over again. Why??? because I did not understand what Umbral Ice did and thus, why Transpose was an essential ability.

For the members here which say read the desriptions: Um....

Blizzard:
Deals Ice damage with a potency of 180.
Additional Effect: Heavy +40%
Additional Effect: Grants Umbral Ice or remove Astral Fire duration 10s

Fire:
Deals Fire damage with a potency of 180.
Additional Effect: Grants Astral Fire or removes Umbral Ice duration 10s

Transpose:
Swaps Astral Fire with a Single Umbral Ice, or Umbral Ice with a single Astral Fire.

No where that I ever remember does the game tell you, Umbral Ice recharges your MP really fast.
Just by reading the descriptions and early game play (single player 99% of the time), it very easy to not Transpose effectively.


As for the kicking, if the other players provided in a reasonable / polite tone instruction on how to use Transpose correctly and you ignored them. I can understand why they kicked you.
I would have just judged how the dungeon progress was going and your responses to the advice.
1. stuff dying at a decent speed? Answer Yes.
2. Your response were also polite (regardless of answers)? Ok, just finish the duty.
