Lvl 4 missioning is one of the backbones of PVE in this game and should be considered core content. The whole idea of alphas is giving them a good range of what Eve has to offer and lvl 4 missioning should definitely be part of that. Especially since alphas have been given access to battleships.
Lvl 3 missions simply aren’t challenging and rewarding enough. Denying them Lvl 4 missions will only annoy the heck out of alphas, it will do nothing to bring them to Omega.
Despite CCP advertising this game as F2P Eve has already one of the worst F2P models on the market, with way too much end content locked behind subscription walls for a “free-to-play game”. If anything, in a game that relays so heavily on player numbers to generate content, alpha players should be given fewer restrictions, not more.
Please, don’t tell me this horrible, greedy, short-sighted idea has been pushed by CCP’s new Korean Overlords.
Edit: If you think this change will really help against botters I suggest you think again. If anything, it will lead to even more lvl 3 bots as hackers will only deploy more of them to keep up their ISK/hr.
