I had always been biased towards energy builds. Loved dual ER-PPC builds. But I had run everything minus LRMs very well until I left.
1) The new skill tree:
My instinct is to load up the weapons skill tree for velocity, heat gen, and cooldown nodes.
Then max out the mobility tree for kinetic burst, hard brake, torso speed, and speed tweak.
After that theres only a few points left to throw into something.
Are those instincts fairly accurate ? Suggestions ?
Are there any guides for this that are current ?
2) Quirks still a big deal ? Any mech recommendations ?
3) Has hit registration gotten any better ? It could be hair pulling at times in the past.
4) Mech mobility is a big deal for me. I like feeling somewhat nimble. I used to find that a lighter and/or more mobile mech gave you the ability to overcome some of the ugliness bad teams would visit on you, versus much slower mechs which could not redeploy at all. I like flexibility.
5) I've read some of the updates over time but i'm not at all current on the ins and outs of the game anymore. I had read only a handful patches notes in 2 years before last night. Insights are welcome

Thanks,
