Whelp, I'm back up and since QMR hasn't graced us with her presence yet(I really should start PMing that suit rat if I want her to join the debate...), I guess I'll have to do it myself. Truth be told, I don't expect anything to change or anybody to change their opinion, but gotta try, for peace of mind, if nothing else.
True, MP is not hard in itself. However, it is significantly harder than SP. From what I recall, only four percent of players finished the SP campaign on Insanity and it's supposed to be hard. As anybody who has played MP will tell you, Silver is much harder than Insanity ever was. When you get to Gold and Platinum, yeah... I'm pretty sure those two would have your casual SP gamer curled on the ground, whimper to their mommas.
Yeah, all it adds is more bullet sponges in form of banshees, atlases, those mother ****** primes(where's my Cobra?) and gives more health and damage to the mooks. Guess what? That makes everything harder to kill. It makes harder for a player to stay alive. So yeah, by simple definition of making things harder on the player, I dare say that MP is, in fact, harder than SP. So I feel some elitism is well deserved. Not that I'm personally engaging in it. As friendly vorcha(now there's something you don't see too often) up there mentioned, it's more of recognizing the discrepancy between two modes. As somebody who managed to solo Gold(scrubby as it may have been), I feel rightfully proud of myself, since I know it's something 97% of player base will never accomplish.
Lets not even go into details such as absence of pause(something that costed me many a medi gel in my bronze days), SP giving you two decoys that will bend to your will and obliterate enemies such as banshees and phantoms thanks to their hitscan powers, something pugs will never do in a regular match, since they will be too busy dying and probably some other factors I'm forgetting right now and yeah, I feel justified in claiming that MP is in fact harder than SP.
Is it the difficulty I would have liked? No, not really. But it's the one I got and I'm happy for it. If that makes me an idiot, well... guess I'm an idiot.
