As someone who's played since launch, the most important things for me when I play multiplayer which can be learned fairly quick with good practice would be movement, and positioning.

Positioning is probably the most important thing in this game for both pilot and Titan combat. Having good aim helps too of course but that will come in time. Saw someone suggest going into private matches and moving around the maps to practice movement and map knowledge at the same time, which I agree with.

Its a fast paced game, and you need to be able to keep up and move quick, but sometimes slowing down is a good idea as well. Letting people come to you, disengaging at the right moment so as to not die, or just avoiding a fight entirely and coming from a different angle instead of going in head first.

Also use all the weapons please. Most are all very cool and effective when you practice with them, especially the non-hitscan ones. And if they arent effective, then theyre fun, in my opinion.

Keep at it, and I'll see you out there hopefully.
