Suppressing monopoles and vortices by introducing large chemical potentials for them in the Wilson action for the SU(2) lattice gauge theory, we study the nature of the deconfinement phase transition on N_sigma^3 X N_tau lattices for N_tau =4, 5, 6 and 8 and N_sigma = 8-16. Using finite size scaling theory, we obtain \omega = 1.93 +/- 0.03 for N_tau = 4, in excellent agreement with universality. The critical couplings for N_tau= 4, 5, 6 and 8 lattices exhibit large shifts towards the strong coupling region when compared with the usual Wilson action, and suggest a lot smoother approach to scaling.
