So beyond the kneejerk reaction, time for reflection. Firstly thing to say is I still regard the proposed ISK to Skill Points change as a Pay to Win feature obviously. Now there is no agreed definition on what Pay to Win means so I am not going to debate that point. Free student tip: You could write a PhD thesis about it. I am just going to say what it means to me and work on that basis. Simply put, it is paying for a competitive advantage, in a multiplayer game.
As has been pointed out, Pay to Win already exists in Eve Online. Buying Plex gives you access to ISK. Your ship just exploded? Pay for another one and rejoin the battle. Want new skills? Buy a character off the bazaar. So why the emotion over ISK to SP?
Let us be clear. I would actually benefit from the change in a significant way. The most skill points I have on any character is 25 million and I have made some dumb choices in the past. Selling skill points wouldn't be my priority, but I can now quickly buy my way out of my current situation. And that is the thing. It is the immediacy. Buying a char was a pain and took time. Guzzling skillpoints doesn't.
For example, I have no PVP skills and can only fly a limited set of ships. Never needed them. If I wanted to bash someone's POS I would have had to hire a merc corp or train for ages. Not now. Instant Oracle and SP, blast away AFK and job done. Then sell the SP and Oracle. Easy instant gratification when you have money. So Pay to Win it is. That there are other pre-existing examples in Eve doesn't diminish the fact.
But ISK to SP changes the game significantly too. I am not talking about CCP now taking an aggressive monetization stance although perhaps in a more refined form that is now their direction of travel. It is a more fundamental point. You will have to play differently and you will have different options available to you.
Another example. I was thinking of training into Outpost Construction to be ahead of the game when the new structures arrive around Spring. Someone has to build Citadels right so why not gamble on the skills you might need and make a profit before others catch up. Well not now. Everyone will just pile in at the last moment once details are known. There is no future reward for taking a risk with skill training now. That saddens me.
There are the benefits though. I currently have two subbed accounts with dual training on one of them. Now I no longer need to sub one of the accounts. Its was basically doing skill queues online to become a rounded Orca pilot, and similarly dual training is no longer needed as I can just buy the Skill Points instead. That saves me £26/$40 a month. The actual costs haven't yet been released yet so this might not stack up but having a live account just to update a long term skill queue may not be the best way to go.
Finally, pity the poor Corp or Alliance leader. It is only a matter of time before their members demand a free skill pack for whatever doctrine is the current fad. Or alternatively, the stalinist CEO who demands the poor noob buys SP before he/she can join the roam.
No, the sky doesn't fall down with this change. But Eve will be different because the change is disruptive. My prediction? PVP will become a more secondary activity to PVE because players will be grinding to pay the rising cost of Plex and Skill Packs. Pay to Win games are like that. Eve will be like that. Maybe you want that. I'm not so sure.
