Seems like my guess, that you are a biased pve player just has been confirned. Typical for players like you to assume that everyone who is even interested in pvp is a casher who needs to prove his "e-kok". Is that the reason why, in your opinion, pvp shouldnt be fun AND rewarding? You forgot to explain the reason tho.
Imagine one thing, there are "normal" players who enjoy doing pvp. When I go to act4 I mainly see c10 to c80 players which probably have been starving for pvp content in the game. Barely any c90 players. They are far away from what you just described as the typical pvp player.
Idk maybe you are quite new to the game with little knowledge about mmos or you just dont care about an overall good game but I gonna explain it to you. Mass pvp in act4 back then was fun for many, all kind of players, AND it was very rewarding, cuz you needed to farm points to get to the raid and get a r7 box. Thats why act4 was always full. So in order to have active mass pvp, you NEED a good reward system for the participants, not only for the top 3. Those pvp interested players dont want to grind the whole day the same raids all over again with their alts to make progress. Thats one reason why the playernumbers dropped so hard. There is zero variety in the game. Already explained why botters wont have a chance, still u bring it up
Rewarding the best players on top of that is a good idea, but not with something that buffs them and makes them directly stronger, otherwise they will just dominate the next month again, thats why they nerfed the medals that the first 3 players get, 10 and 5% dmg and dmg recieved reduced I think, got nerfed to 1%, so that didnt made much sense.
If you only give away rewards for the top 3 players, basically everyone else will get demotived since everybody knows, that only the same maybe 5 players gonna win every month. Idk man, isnt that obvious to you, or you simply dont care about pvp? Why make a statement then? Anyway its going offtopic, im out
