Thats what legendary is for. And skulls.
Solo legendary is there for masochists, and those seeking nirvana.
Don't get me started on skulls. I know some certainly must make the game harder. Others? Not so much.
I only recently made it all the way through CE on legendary for the first time. I had previously been through several times on Heroic, including a run immediately preceding my run through legendary, and had played Pillar of Autumn on legendary once or twice, but never beyond that. Didn't think I would survive, given how much I struggled (the first time) on T&R during Heroic, particularly in the fights preceding and following the grav lift. But I made it through legendary with only a few spots that were impossible if not for my T-16 and bullseyeing skills.
Anyway, during one such trouble spot, I looked for a tip on surviving, the only time I recall looking for any tip. I found a video of some dude apparently playing all the way through the level (TTB) on legendary, and he had the bandanna and boom skulls turned on. :| That's cheating! In my view, that run through legendary also shouldn't count.
But after I was done with my legendary run, I went and sought out the bandanna skull and then activated it just to test my assumption. Completed a full run through heroic (third consecutive run through CE, what a glorious summer!) with it on and, as I suspected, it basically ruined the game. I could have been playing on Easy as far as I knew. There was no joy in never having to worry about ammo, never managing your weapon set, never worrying about the next encounter with Elites as you could simply snipe them at will from afar or plasma grenade them to death from up close (but not
too close).
Bah, skulls. Play the game like it's meant to be played. (Also means solo, forever alone.)
