I am in the top 3% of time spent in destiny 2 with about 1200 hours played. My guy top tree striker titan is in a great spot and it doesnt need to be moved around. That subclass has a really decent neutral game with seismic strikes for one hit kills that you can get back instantly with insurmountable skullfort. Also you get tons of grenade energy back WITH a second grenade charge. And if you know how to play grenades you can synergize really well with it. Plus the top tree is based around high damage for a short period in the super. Middle tree striker is devastating if you can practice with it whether in pvp or pve. I do think the thundercrash super needs a buff on damage but the neutral game is amazing. Shutting down supers and sliding over ammo for instant reload and a short big boost of damage increase on weapons. Along with the fact that the small slam can be extremely useful on weaker targets for an aoe blast. Just got to play the supers right. The bottom tree i would say is probably in the best place though with knockout for constant heals outside and inside the super for a really really long lasting super. Its incredibly hard to stop once one gets going. The increased damage overall as well is huge for the player and will keep any smart player away from you since close range would be at your advantage to dominate. Its all about playing strategically with each super to its strengths and trying to avoid engaging in its weaknesses because not every subclass needs to have an insane neutral game and super. Its all for the sake of balance and strategy to invent new ways to play your characters. It makes it was more engaging that way as a player.
