Offtop:
A sniper - tank tradeoff is balanced because you can't be both at the same time.
A cocktail of drugs from nuka, cigs, psycho and buffout.
Of course you can do only 1 shot per once, and you need to regenerate all APs to do it again. And you'll have only 75% to hit chance in the eyes on 50th hex to 10 AG + BA guy what isn't good. But he is a sniper and tank! Under psycho +x1 toughness and BA, he'll have 10 DT and 60% DR. His high FoV for tank allows him to umm.. tank other tanks faster by imba knock outs and downs and bypasses from 50 hexes so they won't even see him!
You can make 8 LK and 2 ST, then you will have exact 95% to hit in the eyes on 50th hex.
Btw he has carry weight!!1
About carry weight: you already said in 1st post that ST is useless except for carry weight, so.. you want to make it useless at all? Let's remove that stat with CH, make PEIAL, because everyone picks 1 CH anyway except for merc leaders, so let everyone have fixed number of mercs and able to taxi each other, also fixed carry weight for everyone and no ST check penalty and remove ST requirements for weapon at all. I think EN gives too much already by giving you HP, it would be good if ST affected rolls against at least weapon drops and cripples. 1 ST would automatically fail all rolls, so each time someone crits you in hand or leg you'll drop your weapon and cripple limb and 10 ST should give you almost immunity to these. Then weapon handling perk won't be so overpowered. As for small frame, it was said long time ago that it's just +1 SPECIAL, probably they want to leave it as it is, small frame can work something like Jet partly, giving you +1 AP but decreasing DR or work like better criticals but opposite, giving to your enemy +to crit roll against you, then small frame will be avoided by everyone but snipers.
Also when you say there's no trade off, because you can relog/use proxy of your 10 ST pack rat alt, it's already a trade off! You need to use proxy or relog!
However when you need to do anything else but fight, carryweight becomes very important.
Raise your ST or don't take imba Small frame trait.
Yes, it's stupid, it's like:
"I can't sell my guns because barter timer goes so fast! Or I want to buy some guns, but damned Sha Enin has 23942348723 radios and I can't scroll to it and don't know about filter and timer runs out faster!"
"Raise your barter skill."
Will someone raise his barter skill? Of course not! They aren't idiots, they better suffer from it and try again and again and adapt to it. The same with repair skill, science skill, outdoorsman skill, CH requirements, crafting. It works in single player, but it doesn't work in multiplayer, but we still have it and we have a lot alts and we'll have. Dual loggers, triple loggers, quadro loggers, talking to your own alts in front of GMs, FOnline forces you to do that, if you want to remove that, then removing carry weight (or making it good even with 1 ST, but its the same as removing it) is just one of these things and it won't remove amount of alts, you also need to suggest to remove crafting requirements, change outdoorsman skill, change repair and dismantling, change barter, change quests, etc.
