ANSWERED Tomato Router(s) Chaining Scenario

[Flex 0]

Hello,
By Having 2 tomato routers chained Router 1 using  Router 2 as a DNS server together connected to a Router 3 (DHCP) to MODEM (ISP's)  
A computer is OpenVpn over UDP-443 -> direct connect to Router 1(above) using Router 1 as its DNS server.
At this I'm trying to find some of the main advantages for using such an overlapping aka VPN chaining scenario.
Would that be proven beneficial in any way such as
-improved anonymity,better/more protected working environment(better privacy)
-multi device use stand point(cell, tablets etc). 
As disadvantages I know higher latency time, more bandwidth, network collision will be some of the major ones.
Any suggestions?
Regards
