I rarely pvp but when I do I
drink dos plunder.
I see. You're not making an assumption about players leaving due to plundering, it's just obvious. My mistake, I forgot you don't need evidence to make definitive statements. You seem to be ignoring the fact that Oceanic Era added a GB whose primary benefit is for plundering. In fact 3 of the last 4 ages introduced GBs that boost attackers (one also happens to benefit defenders). Bronze age also has a GB that boosts attackers. Not only that several recent historical events made available buildings that boost attack. Your questions are just a form of cherry picking. Look at all changes on the whole.
The fact is, asking questions like the one I highlighted in blue indicates to me that Inno's actions at times make no logical sense so relying on them as a basis for your assumptions also is not logical, counter to your argument.
IMO making pvp optional would in essence remove it from the game and just make it an elvenar clone. Inno already made several GBs obsolete because of a lack of foresight why not add a few more GBs to the list?
