Yes 200 is less of a grind than 300 & 600. With the new marks system, getting 300 or 600 now would still be less of a grind than it was before. & strange coins drop more abundantly now than before. I got 27 a week before TTK came out by doing heroic strikes, & I still get around that same amount without grinding for them. They can call it whatever they want, but it's essentially a sequel. A new armory bigger than vanilla's, a new leveling system, a new story mode (actual story mode, not 3 or 4 missions like the first dlcs), etc. 150 is a steep price to get a year 2 version of a gun you already have, but it is way less of a grind to get them & use them than it used to be. 3 of coins makes it easier than ever to get exotics, so it's not like you have to buy every single exotic you want.
