Dawnblade is a very good super. Top and bottom tree. Someone could even argue for well to be included too (imo its very situational and not worth it a majority of the time) one of the only problems with the two is that it's a skill gap, you have to learn how to use those supers well you can't jump right into the dawnblade and expect to perform well first try. I fear a good dawnblade more than a good bottom tree striker any day honestly. The second problem would be that bottom tree dawnblade doesnt have great neutral game abilities but ive seen some good players out there not even need it. I don't play the dawnblade class at all in crcuible on warlock, mostly because of the skill gap I mentioned earlier, I just don't have it. But I've seen it used well. Arc week made top tree storm boi a god almost, it's not broken anymore but it's still very good. I think warlocks are in a decent place with pvp supers, they're good supers aren't broken (ahem titans) but they could be better by maybe having a lot more good choices like how hunters do, but right now it's playable. I'm hoping in shadowkeep or at least in y3 for bungie to give a bit more love to warlocks
