If your Paragon was high enough you did get options to avoid fighting.... Maybe not all the time but I did notice quite a few times...
But when your opponent is out for world domination your not going to be able to talk yourself out of having to do combat...
My Paragon was always maxed & those moments were extremely rare & were mainly in the first game when ME was still an RPG at heart & not a cover based shooter like ME 2 & 3.
& the option for diplomacy or stealth should always be in these games often, where possible, because Terminator-ing your way through these situations is more Al-Qaeda than British military as far as I'm concerned. & the option for non-violent resolutions should always prove more difficult than just shooting your way through them but then I suppose that goes without saying.
But appeasing the mass murder fetish crowd is what modern gaming is all about & I don't think that's going to change anytime soon, unfortunately. The Splinter Cell games used to be one of my favourite series & the first 4 were pure stealth games & even those are no more than cover based shooters now.
