Hey all, just a little info to hopefully help out, but obviously not in depth as you should be taking time to read the QandA on the official forums.
1. It doesn't matter where you are placed on our battlefield or what building in terms of limiting your actions, whatever class you use will be able to see the same enemy targets wherever you are yourself.
2. Enforcer classes will be placed in the front buildings due to there nature of there health bonus, if you are willing to add stat points to health and pick enforcer then you will be a great asset.
2. Sniper class will allow you to see the first row people and second row to attack, if you see the hq on second row and it has active players in it then attack them as a priority.
3. Assassin class can see a random back row property during battle, again if you see the hq then start hammering there active players.
4. Heavy, not really got much of a specific bonus like sniper or assassin and so is kinda the weakest class in terms of abilities early on. For those willing to save the coins and spend on later abilities for heavy then that is where heavy will come into its own. For example when you can splash damage targets near your target or hit other buildings.
Remember.......
enforcer is strong against assassins
Assassins beat heavys
Heavy beats sniper
Sniper beats enforcer
Remember the above class strength as you will do more damage against the class weak to yours and so we can kill them sooner and for less tokens spent.
Please please remember active enemy players as priority targets first always. A killed enemy player can still attack us but does half the damage which means more of us will be doing max damage for longer.
Keep an eye on what active targets are getting burned by your fellow guild mates as you need to focus your efforts on them also, sooner a target is down the better. Just be carefull not to spend a token as someone else does to finish off an enemy as it will be pointless.
Now for building upgrading.....
In terms of benefiting us as a empire battling guild I personally think we should be donating towards the armoury and hospitals to increase token regeneration and health regeneration.
Upgrading these is a no brainer I think as we can use more tokens so do more damage and get more xp and more coins. Then of course the hospital I'm hoping gives us some sort of passive heal boost or health packs we can use when health becomes low.
