No it won't. Lvl 15 missions give about 30-80 VP with an average around 50 VP. Lvl 90 missions give about 50-140 VP with an average around 90 VP. That's a small VP difference given the mission lvl is six times higher. Split that up to six ways and it's a joke at best.
Only in relation to a zero VP gain would the previously mentioned option be preferable, which isn't saying much at all. Although you'd hit your AI lvl cap far far in advance of when you've collected all your VP. Even if you had taken all the VP in each mission unless you wanted very little you'd still cap out your AI lvl far in advance of the time you collected all your VP.
Most profs without too much trouble can solo self pulled till around the 60 mark and any decent pet prof can go to around lvl 100 or some ways into TL4. MPs would be in about the best shape due to the heal pet and if they go 1HB with an AAD shield while at full DEF. I even managed to solo the odd 150 mission where I didn't get a pod room with a lvl 150 MA. It just takes so long you'd be much better off with lower lvl missions. You're hardly claiming anything new or amazing but the VP gains in missions is still quite low and scales very badly.
You said it was the accepted way and how that is how people should do it to get their VP from mission. Such as towards the top of this one and in prior ones. Which again is not how they were suppose to be done. Just as what people have done with XP stims and do with OST teams is not as it should be done but many do it so it was considered accepted and the norm.
It's not just me, I'm just the regular. Many others start up threads asking for better PvM VP and/or other ways to get it as the system is not working well. Then you can get the items you mentioned just fine with some time. Go to Tara raids with your TL5, farm points, get the GPH. Some orgs do HI raids now and then so you could just get in on such a raid to get it. There is really only one way to get those items. FC didn't by design make multiple ways saying they all allowed a reasonable method of gains but then made one of them ludicrously better than the others. You're making irrelevant comparisons here.
Any time a new thread suggesting some change to LE types (which happen every so often) such sort of comments are made. There are some in the LE forum and many have shown up in the suggestions forum.
Then in regards to tokens they aren't too big of a problem and they've added additional ways to get them over time so you're not locked into just the one way. If you try power leveling to 220 then do all your token farming with guns to get a 2.5k board all at once then that's your problem. If you did it a bit here and there along the way and did some of the quests that give you clumps of tokens as well you'd find token grinding isn't that bad really.
Plus once it's done, it's done. You don't farm a 1k board then when you want to get a 2.5k board have to start back at zero, you just pick up where you left off. With the OFAB armour and weapons you do start back at square one having to get the VP and types all over again each time.
