Why do people still single target mobs when there are 3 or more?

[Taei]

Someone please explain to me why, i really don't understand.

[KeluBehemoth]

Because jobs like Ninja have the worst AOE in game and DRG will burn all of its TP if the 3+ mobs are high health targets.

[Chiramu]

120 TP cost for melee AOE OP.

[Valkyrie_Lenneth]

120 TP cost for melee AOE OP.

Or 160 in the case of Doom Spike.

[KeluBehemoth]

Or 160 in the case of Doom Spike.

and a DRG should never, under any circumstance ever use Ring of Thorns if they AOE.

As a ninja I'll do full AoE spam only with at least 4 or sometimes 5 mobs. It's not worth Kassatsu, burning all my TP, and Invigorate just for 3 mobs.

[Ageofwar]

Because SE gave BLM a bad assed set of solo target skill and weaken BLM's AOE skills back in 3.0

[Morzy]

Ill aoe as a monk with 3. But mind you thats just throwing rockbreaker in my rotation its not that huge.

[AskaRay]

I don't start properly AOE until four or up, aka, too hard (/lazy) to keep my dots up on everything after that.

Just hitting one ability over and over again is also very boring. It's more engaging, at least for me, to work on targets mostly one at a time, except for specific pulls.
