Nyuk would never , go outside of line boundarys, so for them to expand in this world and win, my guess there rate , would be like 20 years, by that time, im for sure someone else would win this world.
Nyuk has some weakness, and easily well defeated if they had to battled like ids did.. but they dont. nyuk will support heavily, lines that are being battled heavy, but once that dieds down so does there defense in that area.. that is one weakness i have seen.. they was lucky i didnt have enough villages in the area to exploit on this and also the battle i always had in k15 area with ids.. so reality, can nyuk be both.. when needed, besides on the front battle lines, dont think so..
Modwar, has enough active players, to win this world. as for most other tribes, it will be hard. for any of them, but modwar is use to sending saying 10 nukes to a village and easily taking over, but are they use to sending 200 nukes to a village and losing all.. I dont know, dont know what they are use to.. but its a question i wander. because if you focus on one area , and think 50 mukes for example will wipe it out, and dont get the wall down.. then you get attack backs from that , what is going to happen.. dont think modwar has face this yet, but you take dosx, ids, and kta, has all face this to something close to this before.. which to me gives those people a advantage over other tribes, no matter what tribe they are in now..
