Ah ya you pretty much just answered your own complaining Titan can be a pretty important role in a raid as can every class you just need to figure that role out and utilize your abilities to play it perfectly. I did a raid with 4 titans and 2 hunters titans are perfect for keeping the portals open during atheon and fist of havoc is a life saver if you struggle with keeping enemy's from sacrificing themselves at certain parts. Every class can play every role in a raid but some If utilized correctly can make boss fights extremely easy.
