Actually for PvE in this game, use whatever the fuck you want thats fun for you. Aside raids and maybe some top tier DPS weapons on bosses, lets not forget that these raids were first cleared with shit guns and 20 light levels below cap. The power creep right now in any of the raids is so retarded you definitely do not need recluse and mountaintop.
The only place that the "meta" really matters is PvP and even then, use whatever the fuck you want. Its not like any of this shit matters. If you are good you will make any weapon kill for you. Go look at frostbolt PvP videos on youtube. He goes into crucible with shit loadouts (thats like his shtick) all the time and still destroys. And while, yes, guns do matter, of course. Waht also matters in destiny PvP is a ton more factors like situational awareness, when to engage and when to fuck off and hide, your aim and twitch skill...etc...
As far as hiding PvE weapons behind a PvP activity, well, this is like the fist time this EVER happened. Usually the PvP weapons are shit. And realistically I remember almost 90% of the good PvP weapons EVER, including Destiny 1, were always hidden behind some PvE aspect, mostly raids that most hardcore PvP people detest like some of you detest PvP.
