I figure i'll share my own experience, thoughts and opinions with pros and cons that i experienced because i see and have experienced both sides of the coin good and bad and i'm not a WoRO die hard supporter or hater.
I didn't play LuminaRO but i did play WoRO from launch day and was probably one of the if not the most geared the first few days till i slowly started to lose interest for various reasons and left like 4 days ago.
I do agree with dice that the server is a cash grab and honestly there is nothing wrong with that, i myself spent a bit selling cash shop points, admittedly when i saw someone with 1.3 billion silver on day like 7 from mostly selling donations i was a bit annoyed. The server is a Midrate with an emphasis on a VIP subscription with a mid end cash shop, anyone who has played RO for any time at all understands Midrate+ VIP+ mid game cash shop with sellable cash shop items is most likely in it for the money and not in it to make the next best RO ever so people should understand what they are getting into.
The server also has free to play ways to get all cash shop items via quest or buying from those who can sell it so it's a pretty fairy system when it's all said and done and to be honest the cash shop could be 100x worse, WoRO's shop is pretty average tbh.
The lag and rubber banding is a result of the severe ddos attacks the server has been under almost 24/7 which Lumina has worked her butt off trying to mitigate by switching hosts twice and upgrading and adding more proxies, Lumina is one the hardest working GM's i have ever seen and i doubt she sleeps much. Despite the severe ddos the server has grown to last time i checked over a 1000 players which is probably like 5-600 considering the 2 clients per pc which is my estimate and is amazing for an RO server.
The server is rampant with kill stealing and i had run into a few mob droppers but outside of pve content players were really friendly but there is definitely a language barrier.
Biggest problems i had was the guild pack system which was the most horrid thing i have ever seen, how quickly the servers economy inflated from guild packs, drop rates, VIP and floating rates, lack of available fluent English NA players/streamersand how insane it was that one player was allowed to/able to obtain 1.3bil in 7 days.
The guild pack itself gave guild leaders who applied 10 million silver and high end cards like raydric and thara and their guild members gained similar cards but with reduced effects compared to the mob dropped ones. The guild pack system caused huge issues for me personally and what i saw, for starters the admin made a guild pack NPC and people were making guilds then disbanding it for guild packs, people were also only wanting to join guilds for a guild pack and had no intention of being loyal which made being a legit small guild difficult to recruit actual players. I could share like 30 discord dm's of people saying they only want to join my guild for the guild pack said that is the only reason they wanted to join and mind you 95% of them did not meet the specified guild reqs of speaking understandable english and would beg me to just let them join for the pack and they would leave.
I spent a couple days looking for a pure NA English guild during launch and could not find one so i made one myself and spent a week trying to get North American players, the server does have a few north American players but from what i have seen most of them do not speak fluent English or even enough english that i could understand and carry on a conversation. The few fluent English speaking NA players i did manage to run into were intertwined in Filipino guilds. There is nothing wrong with other cultures playing a US based server but it personally ruined my own experience not having a same time zone same culture based community to hang with with literally 0 English streamers among all Filipino ones.
The server itself is amazing and Lumina is one the best admins i have ever seen, the server wasn't personally to my liking and that's not the servers fault, but you can't argue or deny the server isn't good when there is 500+ single people playing it every day and climbing while under severe ddos attacks.
I totally recommend this server for anyone looking to get into WoE and pvp fairly quickly but i do not recommend it to people looking for a long term multiple year server.
