You see me, justifying it from the business perspective, which obviously cant be refuted as irrelevant.
If +2 store tomes are the good money maker I suspect they are, then adjusting a game mechanic that would lessen the sale of them would be frowned apon as a for profit business.
The basis of discussion is the rulebooks, and citing precidence for how similar magic works in D&D. Its a consumable one shot item, that works like other consumable one shot items. You were perfectly ready to cite all the precidence you could get your hands on right up to and until you realized that most of it does NOT support the stance you are bantering, in which case you declared all precidence derived from game guides and rules irrelevant.
No, you did not. What you did outline would certainly impact +2 tome sales, because any of those people who would have bought a +2 store tome who are now getting their farmed +3 or +4 tome perminently bestowed apon them would still not buy from the store, resulting in lost revenue.
Simply assuming that they all would not buy tomes from the store because they are quality players does not work in the business world where real money talks. You have to show your work to make these types of initiatives pass, which includes demographics that support that 1337 players dont buy +2 tomes from the store. I would love to be a fly on the wall at this meeting, heh. "But sir / maam, all the uberleet® players dont buy +2 tomes anyhow, so we have complete segregation of the population between those who deped on store loot and those who simply dont buy it." LOL I see the same Vets who are premium try to banter this daily also banter that they shouldnt be looked at as anything less than full VIP because they spend the same or even more money in the store as a full VIP does to play each month. Trying to have our cake and eat it too here I see.....
Looks to me like you were completely willing to cite precidence to lore and rules right up to the point where you realized that 90% of it or so would support those who disagree with this proposal. Now you reject it. It all just magically doesnt count, heh.
A tome is not a book, its a one shot consumable magic item that confers its ability increase then fades away, like a scroll. Irrelevant precidence? I think not. Magical items that have a single use then disappear have a HUGE precidence in D&D, -AND- in DDO. This precidence isnt something to ignore simply because it disagrees with what you are proposing. I have seen no good refutation to this, which is why I have not been convinced as a player as of yet. Declaring it irrelevant is not convincing.
