I cant agree with shortning the radius, regulus is soft and the higher the level and items you go the more it shows. As said people useing mines as grenades thats thier bad a good player will just move and go around.
My self i use mines to set up ahead of me as adefensive position(As they should be).6 where im fighting and 6 in the path i plan to run away in.
I do however feel the number of mines going out at once is a bit much, They should cap it at 2 a throw and raise the total number you have so you can gaurd some flags.By increase i dont mean the old 30, maybe around 20 Same cool down same mana cost but capped at 2 at a time.
*edit* just wanted to throw in the skill that they replaced The Demi only stun mines with, need to be looked at to short range and to little effect. They need to bring the stun mine back as a no damage 5 limit(max skill) 1 plant at a time and it cannot be thrown only placed at your feet.
And to add the the OP's question. I dont have much play time on many of the demi gods but.
The Rook
The stationary weapons really dont do anything that make them worth the points, As cool of a concept as it is they just dont do enough damage.
Pull tower at max skill says you can have up to 8? out and i may be wrong but it seems like after a time they just crumble i never managed to get more than 4 up, also anouther skill that just doesnt do damage to make it worth the points.
Other than that his other skills are great, But the 2 i listed just dont seem to be worth it besides 1 tower you can pull and eat.
Unclean Beast
Anouther one thats pretty close I still think his movment speed is to slow for the role hes supposed to play, the attack speed/Movement buff skill i think should be changed Attack speed staying the same but movement speed bumped up along with his base movement speed.
the oozeing aura you can avctivate,I think maybe it would be worthwhile if it did not damage you but instead cost mana/sec? havent played with it much.
The passive skill that causes the plauge that spreads, the dot it causes has very weak damage not sure what you could do with this one.Maybe instead of the plauge and dot damage when he attacks and kills an enemy they explode and leave a lingering cese pool(for a medium duration 15 seconds?) or something to that effect that deals a greater amount of damage to units caught inside of it.
the other besides regulus i havent played enough really to comment on, this is just my 2c.
