Just completed last hest. Want more.

I know these are used for Teaching players but they aren't really using them. If you want to go and use them for teaching still how about making it next something quite larger like 24 man.
So add 2 lv45 (8 man hests) and lv50 (24 man hests) Completing 24 Guildhest rewards players entry tokens for Skirmish. Need 1 token to enter a Skirmish. Completing Skirmish Trial leads you to the next. Tier2 requires 2 tokens and tier3 3 token and so on. Cap on how many tokens you can carry is 5.

Having 24man hest be something simple like 1 Boss and bunch of adds. Defeat the boss. Takes 5mins to complete.
