Warlocks excels with their powers and not their guns. As a warlock, you need to be in search for armors thats boosts the recharge time of your powers and not worry about ammo. I suggest that you look for armor that speeds up the recharge time of your super and grenade. Regarding 2 grenades, the Sunsinger have a skill that gives the guardian a secondary grenade. In addition, sunsingers can also revive after dying on their own. In terms of armor, I have acquired all Raid Gear for my Warlock which increases ammo for my heavy and special weapons significantly. The armors boosts my intellect by 86% faster recharge for my super, and my stength by 74% faster recharge for my melee. If you haven't done the VOG Raid, then I suggests buying armor from the Vanguard, Crucible, Faction sellers or Xur. From what I've noticed, Titans are just much more resilient. PVE: As a Warlock, if you're playing as a Sunsinger which is firebased, try equipping weapons with Arc and Void damage. I have the Atheons Epiligue Auto Rifle for primary (Void dmg), or The Devil You Know Hand Cannon (even though its not an elemental, but it can kill any shieldless enemy with 1-2 shots, The Fate Bringer Hand Cannon (Arc Damage), and the Vex Mythoclast Fusion Rifle (Special that can be equipped as a PRIMARY-Fire Damage); Plan C Fusion Rifle (Arc Damage), or Light/Beware (Void Damage); Gjallarhorn RL (Non Elemental but very OP), Hezen Vengeange RL (Fire Damage), Thunderlord MG (Arc Damage), Corrosive Measure MG (Void Damage). Its also best that you max out damage outputs with your guns. It helps out with the VOG Raid and Weekly Nightfall, and OP for everything else. See ya around destiny!!! PS: There are no EXOTIC boots as of yet. Weekend Nightfall guarantees a legendary or exotic drop as a reward for beating it, and if you happen to be one of the unlucky ones that gets an ascendant shard or energy, Nightfall do gives you 11 of it. Weekly Heroic lvl 28 gives you 9 Strange Coins. When decrypting blue or purple engrams try having more than five at a time. From experience, I have received legendaries from blues, also motes of light and strange coins too.
