Hello,
I will submit this suggestion for you. However, at present, I believe that both devs and players are generally content with the methods to obtain these items. The best place to get them is Great Plates, where you can get very large numbers of them. You might try this event out to see if it helps you reach your needs.
Thanks and have a great day!

HY there i can see your post and i must say

1. Daily Quests and Missions: Introduce daily quests or missions that offer advanced protection vials as rewards. This encourages players to engage with the game regularly and receive a steady supply of vials over time.
   
2. Boss Battles and Raid Events: Include boss battles or raid events that drop advanced protection vials upon completion. This rewards players for their strategic gameplay and cooperation within the game's community. MyAARPMedicare UHC
3. Achievements and Milestones: Reward players with advanced protection vials for achieving specific in-game milestones or accomplishments. This adds an extra layer of accomplishment and progression.
4. Treasure Hunts: Incorporate treasure hunt activities where players can explore the game world or solve puzzles to find caches of advanced protection vials.
5. In-Game Shops or Traders: Allow players to trade in-game currency or resources for advanced protection vials at specialized shops or traders within the game.

Thanks and regards
