How to unlock old guild event achievements?

Hey,

I started playing SWGOH fairly late, and after some time, I finally found a friendly guild that I really enjoy playing with. However, I’ve discovered that there are two Territory Battles (Hoth) that are considered outdated, and my guild has no motivation to run them. This means I’ll never have the chance to unlock the 45-star achievements for those events, which is a bit disappointing.

>Here are some suggestions off the top of my head. 

• Guild achievements
  • Move guild event achievements to the guild, when a new member joins they unlock the achievement after X amount of time
  • Achievements grant a guild-wide bonus 
• Allow guilds that have reached 45 stars in the past to run a 1-day event where the event can be completed in one day 

I enjoy the game, I wish there was a little more focus on the guild mechanics.

Thanks
