Theres no need for a 20/23/whatever hours cooldown anyway. Just make it "once per day". For example, reset a global timer at 00:00 servertime (or ANY other time, doesnt matter), so you can do it any given time within 24h which is similar to "once per day". Sure you can do the Turn-Ins twice in literally minutes then (1 minute before/1 minute after the timer resets), but that also means you can not do for another 23h 59h which is just fine (working as intended).
If you want to make the summonerer VIP only, why don't just go for it? Why the heck is it *needed* to remove the item requirement? We all know why.
For one that hoarded and bought summonerer items in bulk and spent hundreds of mils, I am not disappointed at all about the no-item thing, cause it means I dont have to buy them anymore, lost zeny or not. What makes me wonder, why ppl like that Havroh guy things theres a thousand Taos killed now everyday with that said "1k+ vip accounts". That means everyone would have to kill the Tao in about 30 seconds, with all the delays (talking to the NPC, 1 minute cooldown after the MVP) its about 90 seconds. Thats 1920 Taos per day if you do the maths at its best.
But that's not how it goes. What really botheres me is the fact theres only 2 rooms. Everyone that camped the last summonerer event knows the rooms will be filled again. Even if non-VIP is excluded now, if that said 1k+ VIP accounts exists, it's not like 1920 Taos gets killed. A good portion will fail their MVP, another portion go for low-tier MVPs for fast zeny (= trading crap MVP Gears for EMBs? S> KVM points!), and another portion of potential Tao Killers just won't do it all all because they don't want to wait 15~30 Minutes in the waiting rooms. There goes the math to <100 Taos per day, which means 0.9 % for a card per day with HE. One Tao Card popping up in 3 Months? I'm fine with that.
If this change needs a change (heck its not even implemented yet), then please make 2 more rooms.
I especially like the vip summoner idea for the simple fact that alot of the items are impossible to get in an open market and it doesnt help some mvps are camped on in outside of the summoner.
Representive for all people posting similar POV's. All items required for MVP summoning can be bought right now (I mean before this patch note). You just didn't want to spend some time or zeny to get them. Zeny, because they might be expensive, time, because even MVPs like Taos are uncamped on Valk Server. Plus theres alot of cheap and/or NPC items, too. No offense, but if that's your point of view for this patch, then your one of the people that won't achieve anything ever anway. Vet players are no vets because they "pay-to-win" (such overdid term), primarly they win because they put effort in the first place. Sure one way to put "effort" is to spent money, but it's proven it's not the only way (I spent less then 30 bucks in WPE, but still I have several mvp cards and god items).
There's plenty (legal) ways how to get something going, but if people refuse to put any effort into anything, then sorry, your not allowed to QQ at all.
