What I meant is he somewhat managed to limit the damage by not extending the consequences past the GMG Arc. Sure enough there was a screw-up, but the Gate incident is a closed case (whether it was done in a good way is another discussion) and there is no longer anything that was caused by the Gate, all things that came through it are gone now and most importantly the Gate itself is broken so won't be used again.

I found the huge timeskip after the Tenrou Island Arc to be worse, as these consequences still go on.
