Thought i'd start a tips thread people can use and share what works for them for Titans. If someone has Warlocks and Hunters do they want to start them and do the same?
Barracades
These are extremely useful if you remember to use them at certain situations. Whilst many go for the larger barricade for the added protection, the 'Rally' Barricade that you need to crouch under automatically reloads your gun. 2 places I've found this should really help is on trials where you may need that last bit of health to knock off your opponent and you usually have to wait to reload, just crouch and pop back up again.
The second place is that it's brilliant for a killer boss with a rocket launcher or sniper rifle. Shoot your load, crouch and the rocket launcher is ready to shoot immediately.
Pulse Grenades
This by far is the strongest grenade the Titan has. It seriously helps to throw it down at the feet of a group before you blast a clip into elite enemies. One significant scenario that it really helps is the Dogs section of the raid. When the dogs start howling and stand still, you then chuck your grenade down initially so the damage is significantly increased. It's also just helped with the recent Nightfall as grenades will regenerate to be ready as soon as the last one finishes.
