Its not even about siege or pvp, you could just farm guards and spam the fort instances for AP and turn in relics. Old AP system is bad and totally not for the West and even koreans faced the problem, which is -as people mentioned- when it was cemented then you couldn't do anything not even as a pvper and old sub.
The nolifers could just take a break and even then you couldn't reach them not to mention take their throne. Generals and above were carried by their team/legion and feed with ap + when not in a serious battle they had to hid behind guards or skip Reshanta altogether, if not for the activities above. Even at 4-Star ap loss was annoying and even 1-Stars were like a big red cross-hair, the diff is with rank the zerg become bigger and bigger.
Honor is ok ,but these systems always problematic, because the dpsing guards/deity mechanic it is disadvantageous to support classes or early tank as temp was, you cant outperform a geared nuke dps.
Well about the shop on Classic, keep dreaming they are profit oriented their hunger cant be satisfied with a simple sub and whales pay bigger, the income is like what you can get now, maybe there is not even long term for a classic (esp Aions). 
The whale stuff just works here in the West too, sadly and the borders were pushed out on what is acceptable. Just read Aion reddit some are defending p2w + sub + f2p/trial + pass there. 
NC Korea is the dev and if they want to push for p2w shop in pair with p2w mechanics, rng then you cant challenge them nor the publishers. If the game is developed in a cash grab sentiment then the only way is to quit, if you dont like it because their HQ is not here. Feedback was given, but they even ignored their korean fanbase and sometimes their whales too.
