Tinker discussion - Your opinion?

[TKF]

I don't know why we should improve the tinker. Only because people can't play with it?

To explain my suggestion:
1.: Tinker would survive a Level-1-Artillery-shot with the correct placement.
2.: Tinker could build 5 towers and still hold a Tech-Mech [5*8 + 3= 43 (food)].

1: If you put the tinker on a flag, he will survive an artillery shot and barely survive.
2: As far as I know, the tinker towers costs 7 food unless this has been changed
