Question: destiny 2 what is the best warlock subclass?
Answer: Top tree (slovabomb) is good in PVP to stop roaming supers and good against (most) bosses in PVE).
Middle tree (Nova Warp) is good for clearing adds and pvp wise decent after the nerf. The 'hold grenade' here is pretty awesome.
The lower tree is the normal nova bomb from D1 and generally not as great as the other two.
