+ one more (two :)... interesting ideea(...):
1. possibility to send counter attack on incoming troops with spy
if enough spy troops send - you can see number and type of the incoming...
if less than attackers spy number included in attack... then nothing to see.
2. possibility to send spy troops to reach troops sent to attack or defend,
with order of change / location - target and / or type mode attack / raid...
(maybe task activated with some gold, for more fun... 
- and the 3rd one...
is understandable why Travian Company maintain his servers on low speed...
but will be more attractive if - at least - some features may be speed up:
- market merchants speed or auctions last up time ...
