they have made the game easier mutliple time over the years, some monsters attack only when you pass right next to them and some have larger aggro radiuses to make certain area more difficult
they made it so you can get xp only from quests so you cant make a bot that just kills enemies over and over again and reaches max level that way. You can reach level 34 in bit over a month if you are dedicated enough to grind everything daily with xp pot and even without potion and guild buff you can get to max level in under 6 months, because later quests give alot more xp when compared to starter islands and irselnorth. But the game is not meant to be played solo
main way to get gold early game is through guests and at later stages quests are still guaranteed way to make gold in addition to luck based drops from bosses and dungeons, crafting is supposed to be a long grind to reach max level to craft highest level gear but you can get craft materials as drops from bosses and dungeons and then only gold you need is for crafting licenses
swamp dailies are unlocked at level 14 which is a rellc back from max level was 18-20, ecen back then they werw supposed to be done in a group and as "endgame" dailies
you can have 2 accounts on 2 devices without getting banned
most likely they dont want to make mcoin buyers have that much of an advantage
as i said before they have made the game and especially first islands significantly easier for new players not to mention daily bonuses and talents and expert skills and better gear on later levels
2500xp is very low when compared to level 34 which requires 83000xp but boss dailies give 46xp without any buffs(58 with only bp buff) and yellow guests give several hundred
