I need SMN help

I need to know what I need to do to try and carry. Because in snowbally matches I can do alot when I can turret but it just seems with the CDs and the need to...hardcast alot of things I cant turn a close game if not actively hinder my team because once ive burned through everything and have to ruin spam im nigh useless. Also LB doesnt have that "i just wiped someone off the map instantly" feel that most other dps get. People guard or recuperate through Bahamut so easily. Even going Astral - Fester - Fester for maximum spike it just feels like people can just walk away.

So please high elo gods please tell me how to solo carry the way alot of other jobs i see doing.

I do a TON of damage on SMN, especially with the LB. Basically hang back and cast Ruin to build your LB gauge. Use Slipstream and Mountain Buster to zone the enemy team. When my LB is soon to come up, I let all my cooldowns come up. First I'll zone with Slipstream and then Mountain Buster. Then I'll use LB on the group. As the LB is going off, I jump in with Crimson Cyclone, pop a Fester, Crimson Strike, Fester. Then mop up with Enkindle Bahamut and Astral Impulse. The burst in that combo is bonkers.
