If I think about what currently keeps me from exploring all that Eve has to offer, then it boils down to one problem: if I fly into dangerous space, I risk my implants. If I however jump into a clone without implants I drastically lower my learning speed. So I sit in high-sec and wait for all those skills I want to learn to complete so I can finally play the game, which is: never.
Removing learning implants all together (and give players a permanent +5 skill buff instead) would make it easier for people to move away from high-sec, as the risk in form of the ship you bring is easier to calculate, and yet you do not loose anything from reducing the price-tag on your kill-mail.
Effectively currently leaving high-sec means you need to spend X skill points to do so, which isn’t very appealing.
It boils down to you wanting faster gratification. I have not used attribute implants in years in my PVP characters and have been training just fine. You want the implants. It is your fault for putting them in your head and you hold yourself back. Deal with your own incapacity to live without them.
Upwell structures are great for short-term things like sudden PvP, but if you want to do some longer term exploration i.E. and you probably won’t even come back to K-space anytime soon, then upwell structures are not going to fix the issue.
It is not about the pricetag of the implant, it is about how much more expensive they make your ship. If you fly a 50m covert ops, that means with implants this ship is now worth 200m. And if you use cheaper implants you are back at the issue that you effectively need to sacrifice skill points to enter low/null sec.
Money is always a problem. Implants that boost certain PvP-related values are optional, and if you dare to bring that boost into PvP there has to be the risk to loose it. The big problem is that learning implants are not optional, they are more or less mandatory.
The vast majority of people I know in Eve don’t leave high-sec because of their valuable implants. But they should. You cannot change all people, however you can change a flawed system that makes them stay in high.
Training Implants are purely optional. You don’t need them to do anything but train faster. That comes at a cost of what else you might put in that slot, or the cost of just losing them, and considering you can get level 4’s just by running missions… Eh.
And those training points can be directly returned as ISK. If I would just not use training implants yet want to learn at the same rate as everyone else, I had to pay about 0.7 to 1.5b per month for skill injectors. Just to put a price tag on them.
Now we are getting closer to the issue. If I am scared of loosing ISK because I leave my safe space, I can always use a cheap ship. But the learning implants make my death stupidly expensive, and if I don’t use learning implants, I also loose a lot of skill points aka money.
It’s a meaningful choice because it has real consequences.
A great many people go without learning implants and instead PvP with much more expensive implants in their head. It’s a choice they make for the performance benefits.
You want training speed, put them in. You get a massive discount on the price for backing down a level, with a fairly small impact to total training time, so maybe limit your risk by limiting your reward?
Why should every other player in the game be denied that choice, just because you find it onerous?
