In all honesty, back when I binge played CS I kept saying any game that looks like CS is just a rip-off, hence R6-S came out and I kept giving it backlash and hate, considering I thought all it was, was a new CSGO game that's trying to rip it off. I recently acquired the game a couple weeks ago, and actually love the whole new aspect to it, it's actually more planned out that CSGO and is such a better E-SPORT you actually have to plan and coordinate with your team efficiently, now you may say you can do that on CSGO? yes, but there isn't much of an aspect to CSGO..

While on Rainbow, you need to make sure you're secure and have a fully competent team covering each side of the bomb/hostage and making sure you have equally spread abilities to counter the enemy. Big +1 from me.
