I really don't understand the hatred on this decision. I play Destiny regularly with my friends, and I am almost at 100 hours played. I have completed both raids, and frankly, neither are as fun as normal strike missions because most fireteams you join (as you require six people) will want to cheese the raid, or follow everything to an exact formula to defeat them. They become the most chore-like activity in the game, because if you have someone who is new to them, it takes a little while to teach them the mechanics. The first time you play, it takes quite a while to defeat, but once you know what you're doing, they don't offer a stark contrast from any other mission. As a result, my friends and I do not play them very often.
It seems to me people would welcome a new game-mode, even if it is horde mode, because that will offer scaleable difficulty for smaller parties. Horde mode was well executed in Halo ODST, and Gears of War comes to mind as a game with an enjoyable horde mode--so why wouldn't it be fun in Destiny?
For those of you who have already sunk hundreds of hours into Destiny, how much playtime did you want to consider having gotten your money's worth? I think as I am about to eclipse 100 hours, it has been well worth the $40 I paid on Amazon, and with the extra $20 for the Season Pass, it was the cost of one MSRP package.
If any company deserves the benefit of the doubt, I would argue Bungie has earned it, after releasing one of gaming's most iconic series in Halo, and being amazingly accessible to its fans and community. It's confusing to see the vitriol stemming from this decision.
