They did... but for co-op
At least that's what I think. Having a balanced party is the way to go, or 4 medic Sirens.
The game feels very imba in terms of single-player balance.
Co-op inherently has an advantage in that I assume a party would have to experience a full wipe for the boss to reset. In TVHM, it's incredibly easy to get one or two-shot by the bosses. I fought BN-K3R as Siren at two levels below its level -- you can imagine how many times I had to retry after getting one shot by his rockets before finally successfully whittling down his HP.
And yet the loot quality is actually much worse in solo. Considering the level of difficulty soloing, they could have thrown you a bone in terms of loot. Logically, you'd think they would have the same quality of loot as for co-op, the only difference should be that co-op gets instanced loot.
After getting Siren to 50, I decided to try Gunzerker next. I just went from level 21 to level 25 in about an hour to hour and a half farming Slappy and I don't even have a Bee shield yet. Huge disparity and imbalance in general.
Why do you need eridium for anyway?I heard you need some for the raid boss but is it just to unlock it or it's everytime you want to fight it?
You use it to open up the area to fight Terra. Once you leave the zone, you need to pay the iridium again the next time you visit, but you can stay in there and keep fighting him as much as you want by quitting to main menu and loading back up.
Bosses are sadly easier than normal mobs because of the cover "exploit".
Abusing bound boxes and geometry might be considered an exploit, but I don't see how I would even be able to solo Terra without "exploiting" cover if I can't DPS him down as soon as he spawns, considering how cheap threshers are.
- one swipe from his tentacles will knock you clear off the map for an instant death, and are almost unavoidable
- the spikes he fires can't really be outrun
- all of the tentacles he spawns
