Max leveled just now. The Strike mission was fun, but oh my god is it grindy with those bosses. Very exhilarating though.
Final thoughts:
I wasn't interested in this game at all before this. Now I might be all in.
That was my opinion at first as well, however, once you get some gear at lvl 8 the bosses become way less grindy.
I think the main issue is that the drop chance on loot is pretty low for the first few levels, so you'll be doing shitty damage.
