After 2 weeks of coming back, it is obvious that this game is cashing out on its old legacy. It used to be an amazing game I admitted. But if you're looking to come back for the good old days, there's not much iRO can offer here.
1) Pay2Win system:
It is against term of service to purchase in-game gold (zeny) using real cash. Yet it is ok to sell your warp portal energies into zeny ( which is obtained by cash). So the only way to cheat is to give money to WarpPortal.
Cash shop items also rendered many other in-game gear useless. And the only way to upgrade safely to +9 is to choke up $20-$50 in game cash for it.
There are so many bots in this game. Honestly I only see around 100-300 active players in game, and the rest are either bots, vend bots, or afkers. Worst part is some bots are actually ok, I see them roaming around cities buffing people, and somehow that makes everything ok? Also there's this thing called ragial which is obviously run by third party bot systems.
3) Lag issues and DDOS:
It's 2015 and this game is still constantly lagging and I am using 75mbps fiber optics internet. Also their servers keep crashing very often, and usually at the worst time of the day.
4) Immature game design decision:
For those who paid for VIP for leveling, the GM sometimes decide to change the turn in quests so impossibly difficult that only godly geared veterans can do them. So you're likely wasting 1 week of VIP time afking or slow grinding your level. Also good luck finding public parties to play with outside of the turn ins.
5) Slow customer support:
It literally takes them days weeks or months to answer ticket issues. Worst part is they will just ban you and give you no reason sometimes. So you have to open them a ticket just to find out that some of the items you bought may came from a cheater, causing you to have weeks of downtime.
6) Good luck finding players to play with.
Finally, good luck finding enough players to play with. It's a dying game, and most of the time you'll be spending time waiting for a party to setup (30min - 3 hours recruiting time just to setup 15 minute leveling session)
I'd say save your money folks. The old days of Ragnarok is loong gone.
