FLEETS
In general DO NOT USE fleets.
Use local area only or hold position.
There is one time I would recommend using fleets in a PvP match. This is where you are in a defensive position and building units in your factory. In this scenario.
- Create a fleet.
- Set the fleet to hold position.
- Set the rally point to the fleet icon.
- Newly built units will join the fleet and automagically set themselves to hold position.
- Disband the fleet when you start attacking.
This prevents individual units from suiciding themselves on the enemy fleet.
Another strategy some people use in this situation is to set the rally point from the factory world to the next planet that DOES NOT go past the enemy fleet. This allows you to also build units without them suiciding themselves. A common counter to this approach is for the enemy to move their fleet in the path of the units jumping to the next world and destroying them with FF before they jump out.
EMPIRE TREE
Do NOT use the empire tree to issue attack orders. It seems like you should want to but using the shift clicks on the empire tree has unintended consequences- mainly time related as empire tree doesn't take into account distance, time to turn units etc. The better way is to micro focus fire to limit how far your units move and turn to maximize damage.
The empire tree is good for selecting your units or watching when units might be in trouble. They flash red if they are being attacked.
SELECTING UNITS
Learn
Alt+[Left Mouse Button] - Selects all units of the same time
Shift+[Right Mouse Button] - Creates a chain of orders to execute
Hold [Alt] - Shows Red circle for engagement range of Weapons.
Hold [Alt] + [Hover mouse over ranged ability] - Shows purple circle for Ability range. This is good for AOE's like MB where you want to make sure as many units are possible before you micro cast the ability. You should also consider turning off autocast on some abilities to maximise their use with micro.
