Leveling Weapons On Higher Levels

[Exodia-Doomsong]

So I thought I'd be able to level weapons faster on higher levels...like say start directly on level 15 or so.
Easy kills yea but the problem is...level 4 mobs give 60 experience and level 55 mobs give 87?

I could kill 5 level 4 mobs in the time I kill 1 level 55 mobs.

So is there even any point in doing high level missions? Mods? They seem to drop randomly I got a few mods where the wiki stated wasn't possible getting. Though I am still missing multishot mods and I've tried going to where the wiki states with no luck yet.

I encountered the same thing, but its also worth bearing in mind that higher levels will not just have that tiny boost in exp per enemy, the higher levels also tend to have a S#&$-ton more enemies. And a larger % of them will be the high exp heavy units. The best levels are generally agreed to be Kappa and Kiste, grineer mobile defense.

Good luck !

I see, I'll keep that in mind! Thanks!
