The people who complain about off-grid boosting don't understand where the problem truly lies. It's not a matter of your enemies getting this great advantage that you aren't getting, but the fact that you're fighting one against two, and complaining that the odds aren't even. If they force boosters on-grid, or removed them entirely, all that's going to happen is that those people are going to bring a logistics ship instead, or simply engage you with two combat ships, and you'll have the same exact problem that you're complaining about right now.
But as I've mentioned in previous threads like this one throughout the years, making boosting a grid-only affair is actually a
bad thing. For example, look at my post
here. Actually, I'll go ahead and paste it into this reply:
I've said this before, many times, and I'll say it again: off-grid boosting is an equalizing factor for battles with numerical disparities.
If two forces of different size are fighting each other, and the boosting can be done off-grid, then the forces are proportionally as efficient as if there was no boosting at all, assuming no significant differences in boosting skills.
If two forces of different size are fighting each other, and the boosting can only be done on-grid, then the larger force gets a significant advantage over the smaller force, because:
1. the larger force is more able to defend its boosting ships due to being able to proportionally field more logistics
2. the larger force is more able to attack the smaller force's boosting ships because its superior DPS overpowers them quicker
3. the larger force, by its very nature, is more able to field backup boosting ships to immediately replace the ones lost due to enemy action
These three factors combined would make smaller forces objectively worse off when fighting larger ones, and that is on top of having a numerical disadvantage, than they are today.
So, if you advocate on-grid boosting, you're basically saying "I like to blob my enemies, and it would be nice if CCP made it so that I could blob my enemies more efficiently. Please, CCP, change this mechanic so that I am able to use my organization's superior numbers to an even greater advantage over smaller parties. Creating such a disincentive to small-scale pvp would really help me further my own goals at the expense of the game as a whole."
