532A & Level 5 software ok?

We are looking at purchasing a number of Routerboard 532A units and would like to run the Level 5 software. Two reasons mainly, 3 years of updates and when 2.10 is released routing support. We recently contacted DoubleRadius for a quote and received the following reply when asking to upgrade the units to Level 5 from the start:

Mikrotik recommends keeping Level 4 vice upgrading to Level 5.

Mikrotik, can you confirm this is your recommendation? Why? I am hoping that I just received bad information. Thanks in advance!

I can’t believe they will require level5 for routing (rip,ospf,bgp),l I can see BGP being extra, but not rip/ospf…

Take a look at:

From what it looks like the routing protocols are L5 or higher.
