Back in the day companies would normally work out plans for talent months in advance were they would be able to know where they going feud to feud. WWE stopped doing that a long time ago, but this feud has had all the signs of an old school including a slow burn. Factoring in Randy's injury this program has been going on since I believe No Mercy last October which is a very long feud for the WWE nowadays. If it was me I would have liked for things to simmer a little more between Orton and Bray and even given them a longer run with the Tag belts then they had, but having them blow-off at Mania is the only logical way to end things.
Now if you look back to 2014 and the months prior to Wrestlemania 30 you would find a very similar feud going on between the Wyatt Family and Daniel Bryan. Part of me believes that this is how they wanted go with the feud between Bryan and Bray, but do to the rise of the "Yes Movement" plans were changed and I think they put a pin this feud idea. If you think about in late 2014 the Wyatt Family would dissolve anyway making way for lackluster singles pushes for Rowan and Harper, but had they ripped the family a part like they did in this feud then things could have been different for both Harper and Rowan.
Looking ahead to Wrestlemania I have nothing, but the highest hopes that the momentum these two have built and the story they have told will come to the best conclusion possible in Orlando. The Brand Split may have it's negatives, but this feud has been one of the many positives we should be able to take from the split. Seeing more feuds like this take place where it is given a chance to develop and become something more then a filler feud would be a breath fresh air in the WWE and invoke us all to have more confidence in the creative team.
