Please add a limit to the rng grind the reason this hasn’t been added at this point baffles me. For example after your 5 or 10th horde mimic battle the drop is guaranteed. At least this way there is a finish line people can grind towards.
The rng was much better the first few weeks the achievement was added. So the reason this hasn’t been done cant be a fairness issue. If that were the case you wouldn’t have added an achievement like this in the first place. Proven by the fact some stumble into this whilst others put 100s of hours into it and still don’t have it.
How many players have you lost because they are sick of an endless grind that may never happen? Getting the horde mimic battle is already hard enough. Please fix this multiple year grinds are highly disrespectful to your player base.
Thank you from a highly frustrated player who is hopeful you can still make this right.
