Mr Moon doesn't just watch anime though he eats and breathes anime Imo soldier is a great allround class and a great starting class. Decent sized health pool (200) with a powerful primary and a shotgun as secondary (imo the most useful secondary if you don't count demomen). For starters, just spamming rockets all over the place will get you loads of assists, if not kills. As long as you remember to aim at your enemies feet. Rockets do splash damage so hitting rockets on the ground next to your enemy will still do a lot of damage.
A bit outdated, but for the basics it's fine.
