No one praises Reach as the best, just praise it for what it does better (ie forge, campaign theatre and scoring, textures, armor ect). Halo fans hated Reach and Halo 4 multiplayer went a step further making it worse (ie perks, kill cams, can't disable sprint, ruined infection, no campaign theatre/scoring ect.). With halo 5 getting rid of armor abilities and possibly perks, I see it getting lots of praise and only the halo 4 kiddies will cry about muh armor abilities and muh modern shooter!
