Only way peeps are gonna complete tower is if they hit it religiously. Like as soon as the cooldown is over go again and again until it's perfected. It isn't hard per se. Just a matter of having your teamwork down and that comes with practice
LOL funny you say that Landon. I actually pimped heRO to a few folks in another game I've been playin. They wanted to try RO and I sent em here.
