Request to Dev's. Tune Titan HM.

[leprov]

Skill is where you can magnificently swiftly summon your Titan-Egi and keeping it alive while at the same time killing off 4-monster mob in Stone Vigil while your Tank is lying on the floor face down
Skill is where you gracefully switch between Cure and Cure II to maintain your MP while keeping the health bar adequately full
Skill is where you quickly whip out Mage's Ballad when the White Mages are getting strained long before they actually start calling out help.
Skill is NOT where your ISP is trolling and your latency skyrockets and you get struck by Weight of the Land when you're obviously standing 5 yalms out of them
In short, skill is Garuda, Titan is just bad, because it relies exclusively on something you can never control: your latency

So you mean that skill is pressing the buttons, but only the spell buttons, not the one that could make your char move? If you have one second lag, you will have troubles, and not only on Titan. And if you don't, you definitely should stop blaming lag. You actually would have troubles in any MMO if you the lag your pretend you're having. (And yeah, first time I went to Titan hard, I died to plumes while seeing me outside. Then I stopped blaming lag)
