personally i like the new rocket launcher, it turns him from an all around, no situation he can't handle class into a
defensive powerhouse.
why the emphasis on the defensive? it feels awkward trying to rocket jump with it, having to load it up to shoot it, and if you overload it, it backfires, so you can't hold it for when i need it. and if you try to use it offensively, chances are you will die trying to shoot at somebody, as the loading it up just to fire makes it ever so slow enough to leave a window to be hit with whatever the foe has waiting for you.
my only problem with it is that random crits make this launcher feel too powerful when used for it's purpose.
