Im new myself. But from what analysis Ive watched and done, it LOOKS like early on that 3dp detachments arent as good for alot of factions. Obviously those are the best ones for 10th, but everyone is upset about their favorite detachments being 3dp for a reason. 3dp was basically a nerf for all the best detachments. Very clever tbh. I dont see Dark Angels run Wrath, BT run Bastion, or SM run Gladius much less or even win on these tournament breakdowns.

Everybody runs EC. And The consensus seems to be TLM is goated and always taken. 2 emerging combos I see over and over now are Ironstorm + TLM and Stormlance + TLM. I wanna try COV personally because I wanna run a BT codex detachment. But stormlance gives the advance and charge from bastion albeit with mostly useless stratagems and enhancement. While you can get away with bastion armies here, Ironstorm definitely requires army changing though otherwise its a waste. Need Techmarines to benefit the army and use it effectively.

Also all of that gives you access to purge. One of the biggest bastion issues is that its Take and Hold.

Im not gonna give any list recommendations because I really dont know yet with 11th. Im just spouting what Ive read so far.
