I hated them too but after a few Raids and a few dozen PVP games I can say I'm honestly a fan. Maybe wait to see what's involved in the guns? I have a suspicion it will be an involved and engaging process to upgrade (think the upgrade path of Necrocasm, but not sucky). Lots of quests, bounties, XP, purchasing, etc. But what do I know? Lol If true though, it might not be worth the chase if you dislike the Titan in general.
