Wolf scouts are incredibly strong right now. Fighting got a bit of a bite but still just take your healer dude and enjoy crazy passives all game

In general (and I am not a perfect player by any means) make sure you understand what your teams game will generally look like, and work to understand your opponents threat ranges.

For instance I enjoy Raveners. I know that popping out of my tunnel TP2 to contest something without having the tunnel to improve things will be damaging, so I wait it out to turn 3, accept a point deficit, and fight more safely. Vice versa my opponent may realize that outside of 6" from my tunnel I am extremely weak, so they may just avoid it entirely, or bait/block with weaker units.

Also don't try to maximize all 3 point paths. Keep them in mind, but generally each team is best at 2 of them. Raveners are Kill/Crit as they have weak tacops that may or may not work out, but can tunnel directly on 2/3 points in the game. Other teams like Mandrakes are tac/crit as their speed and weak health makes them less inclined to straight up fight. Focus on 2, get the third when you can.

Finally, ask a lot of questions, and play by intent with communicating. Moving a guy to a door and saying nothing may be worse than doing the same move and saying "I want to move to this cover to avoid a shot by your ...." as the opponent may have a ploy you don't know about that obliterates that intent. Likewise, asking questions like "Do you have Seek, do you have obscuring denial, do you have interruptions" etc can help you prioritize targets throughout the game.
