Well, if you have 2 systems, and one fails, then you presumably need to be able to run everything you need one one box (or N-1 boxes, where N is the total number of systems you have).
In general, running active/active is way more complicated to build, support and troubleshoot than active/backup. Most likely, you think you need load balancing, but you really don't. Or, if you do to support your workload, then you're going to be having a bad day when you loose a system.
