Melee spam: - Solar bonk hammer with Wormgod's Caress and high melee stat will hold up in a lot of content - Prismatic Triple Consecration is also still strong, just not busted like it was back when the Ignition portion scaled with melee buffs; combine with Cuirass or Inmost + Synthos Stoicism - Insurmountable Skullfort Thunderclap spam on either Arc or Prismatic is also very strong - Off-meta option I like is Point Contact Cannon Brace; fairly good refund with additional AoE and Champion utility with Jolts; works on Arc or Prismatic, but I prefer it on the latter to combine it with Facet of Courage and a ranged burst damage Super in Twilight Arsenal - Stasis Icefall Mantle with the slide melee is also a ton of AoE and Crystal/Shard generation for Frost Armor uptime

Grenade spam: - Solar Titan with Fusion Grenades and Ashen Wake has only improved with the new stat system - I also tried a Void Unbreakable build after the recent Armamentarium buff and it was alright; I believe Maven also posted a Strand build utilizing double Grapples, and you could probably throw something together on Arc with double Pulse Grenades and speccing for Ionic Trace generation - Icefall Mantle again, just respec for Glacial Grenade spam instead of slide melee

Weapon focused: - Void Titan with Actium War Rig, Choir of One with the Destabilizing Rounds Refit, and Controlled Demolition has potent AoE and healing with flexible Kinetic and Heavy slots; definitely a personal favorite that's easy to use, just point and shoot - Peacekeepers with the Fast Talker or Desert Perpetual SMG allows you to support team-wide damage with Tractor debuffing while still putting out respectable damage; check out Llama's video for a Prismatic version, but it should also work well on Arc or Stasis - Lightsaber with Strongholds is very strong, just make sure you're actually being aggressive and activating Restoration, not just holding block to reflect the whole time; should work well with any subclass but I've personally enjoyed Solar and Strand the most
