In all fairness, if I recall/understood correctly: Welles was always going to create the particle accelerator explosion (hence Earth 2 Welles doing it too).. Thawne wanted it sooner, so he replaced Welles and pushed up the timetable.

So… I haven't been following wrassling too much in the past few years. But apparently the highlight of Wrestlemania is Shane McMahon as a menacing and credible threat to The Undertaker?
