Hiya so I play a wizard and I love the fact that your are possibly changing the gtaoe mechanics. I'm a believer in if you have small numbers or large being in a tower or keep/inner keep should be at an advantage. With the current state of gtaoe this is not the case. Your a sitting duck all it takes is 6 casters with gtaoe and your permantley taking damage in a location of 350 radius. Now the changes that have been spoke about are interesting but I honestly feel your missing some maybe better suggestions. Taking line of site into consideration you may as well remove the ability because it will then be a stealth popping tool only. My idea and I think would be the best option is remove the ability to raise and lower your ground target. It should be casted as normal but in line with your character. So if your outside a tower and you gtaoe you can only get the ground floor. If your in a keep on the oil level you could reach the ground floor stairs so on. This would introduce a more comfortable approach to the current mess of the spell I beleive. Cool downs wont work I think it's not a cooldown issue. Line of sight will remove the ability from use. Staying as it is well I suppose we are use to it but it needs a change. I honestly hope you read and could maybe look at introducing the vote where you remove the ability to raise or lower the gtaoe rather than removing the ability all together. Thank you
