Its ok because when they patch pushing bosses off then the titan and warlock won't be so useful anymore and will become useless in the raid. In the 15 raids that i've run as a 29 Hunter I die the least. The fact that everyone thinks because warlocks have self-res they are useful are sadly mistaken. Why would you need self res? The answer is because you died and had to revive yourself and what makes you think you won't just die right after you res. Not a valid reason to have a warlock.
