Rooseus:
1) I agree with you on your point if what you are referring to is "Massive Armor". If you are referring to just regular unb III, prot IV armor, then I think you still make an interesting point. However, I don't believe that there being a penalty of dropping armor isn't enough to deter the use of it. Some people, perhaps, but then you go on to saying ..."oh, I know this will decrease the amount of premiums." Are you serious, man? You need to understand this reality: premiums make this server possible. More to the point, your "solution" of premiums dropping armor isn't much of a solution if the non-prems don't even have a chance of taking them down to begin with. I believe my proposal of iron Massive Armor is more reasonable -- it actually attacks the problem at its source, which is to close the equipment gap between non-prems and prems, while still maintaining the unique feature of diamond armor to premiums.
2) With your point regarding the McMMO plug in, I completely disagree. There is someting we need to take into consideration: balancing what the server staff perceive to what the server -should- be VS. what the MassiveCraft players want. There needs to be a balance, and your proposal is much, much too extreme. It completely isolates an incredibly large amount of players who enjoy the McMMO plug in.
You also say, "The McMMO plug in doesn't fit". What are you reasons? You give none. You simply state what YOU alone want, and what you think is best for a fraction of the MassiveCraft player base. The solution I propose, however, is a middle ground between the status quo and a new plug in altogether: simply tweaking and customizing McMMO further to improve PvP and make it more fun.
I do consider the whole skills specializations a definite possibility, however. It leads to a whole new dimension of PvP and encourages cooperation between players... an effective army will have to mix and match different classes in order to outmatch another unique army. It may do well against one specific army, but not so against a different combination. And I *think* this is definitely achievable in McMMO, if not already suggested on the McMMO main site.
3) No comment. I think the whole surrendering issue is more of a roleplay etiquette/politics issue, rather than direct PvP combat issue to be honest.
