I noticed we do not have a Tactics thread up yet, and I'm sure new players are curious to hear the RS veterans talk about their experiences, so here it is, feel free to post your tips and tactics you use on whatever faction you like to play and hopefully lots of people can gain a great understanding and knowledge on the particular factions that interest them.
This can range from simple Campaign strategies or Battlefield Strategies as the discussions can be endless, so feel free to post your insights here.
