You'll actually need these defensive additions [to your SG base] to safeguard your group's captured power crystals, which you can be add to you base after you seize control of them. Captured crystals grant powerful bonuses to all players in a specific group, like the ability to deal increased damage in battle, or to receive bonus experience points after defeating enemies or completing adventures. We're told that Cryptic plans to include several different types of crystals, including generic crystals that provide minor bonuses, as well as a few types of extremely powerful, unique crystals that will likely end up changing hands among the most powerful hero and villain groups on each of the game's servers. This is because groups of both villains and heroes can stage raids on each other's bases to attempt to steal away the power crystals. Considering how powerful some of the rarest crystals will be, most groups probably won't give them up without a fight (or at least, without buying a chaingun turret or two)
This sounds really interesting and I'm considering coming back to the game as a result of some of these new features... I do believe the devs will work to address the endurance usage problems that E.D. is going to introduce as well as the tanker defensive power problems it will also introduce. Once those birth pangs are fully worked through things should be a more even playing field for everyone.
Under the current enhancement system (without E.D.) everyone is going to *have* to take perma-Hasten if they want to have any chance at all of beating another SG to protect their power crystals. Think about it -- one SG is made up of characters who all have perma-Hasten while their challengers is a group made up of some with and some without perma-Hasten. Clearly the fully perma-Hastened group will have an advantage in being able to attack more frequently. This has to be addressed, otherwise min-maxers will always have the power crystals and the fights over these ingame objects will be reduced to a battle between only SGs made up of power gamers. Anyhow, just my .02 on some motivating factors behind ED and it's effect of ridding the game of perma-Hasten.
These new features are exciting... It's going to be *so* fun pwning furry/rp nerd SGs and ganking their power crystals. I can't wait.
