I am a big mikrotik fan, but am increasingly finding that my life is dominated by having to work around and deal with mikrotik bugs, Whilst it is good to be add news features every five minutes, can the developers please concentrate on get the code stable and bug free before pushing it into production builds.
Examples of issues that I am currently dealing with
VRRP interfacess becoming invalid when changing priority

OPENVPN dieing and requiring a reboot.
http://forum.mikrotik.com/t/response-from-support/35346/1
Network addresses not appearing in the routing table on reboot.
These are bound to VLAN interfaces, which have VRRP interfaces on top of them, 9 out of 10 will come up typically, it is not consistent. reboot and cross your fingers that it will come up ok. The fix is easy enough, just jump into the addresses list and then disable the affected address then enable it again and it jumps into the routing table.
Other ones that I gave up on and have moved on from, circa 4.9
Custom DHCP option values breaking DHCP server.
Web proxy broken
