Antero in Tyler Co WV

I was recently told by Antero I own 4.500000 gross acres (0.00794 net) of mineral rights in Ellsworth district of Tyler County, WV. I think hiring a lawyer in this case would cost more than the value of the mineral rights. Antero is offering $200 signing bonus and 14% royalties in their cover letter. However the lease says $10 and 12%. Do I have to sign a lease if I don’t want to? I’ve heard they will “force pool” me if I don’t sign. Will it cause me legal issues if I don’t want to sign their lease?
