Hiya,
Tone down the amount of drones, grenades she uses, she used a drone every 5 seconds and over 20 grenades.......we are limited to a maximum of 7....limit her to 7 as well and even at skill tier 6, my drone was on a 17 second cooldown, but my weapon damage SUCKED, her weapon is WAY too high, while her clearly being a skill based enemy.....pick one, not both.
Otherwise, it is challenging for the sake of it, this is just like Keener, overpowered enemy.....nerf the hell out of these enemies, they should NOT be that strong.
sending out drones within 5 seconds of it being destroyed is not possible, cause i have had as much haste as i can find and it still 15 seconds cooldown AFTER it is destroyed, so it should be 15 minimum between drones, not within 5 seconds.......the Grenades do not regenerate, unless she is using Timelord science, where her belt is bigger on the inside, she needs to be limited to 5-7 grenades....depending on their type.
I am all for challenge, but when the challenge breaks the rules of the game, that is when it is poorly designed and needs an overhaul.
