What reasons? You're shortchanging yourself, the raid is far and away the coolest thing I've done in this game--and I already loved the game before that. Find yourself a good guide to take you through your first run and it'll be enjoyable and shouldn't take more than an hour and a half to two hours and you'll be hooked. The subreddit for Fireteams is a great place to look, or even these forums would probably turn up a kind soul. Hell, once I've run it a couple more times, I'd be happy to take you through.
