1. Can you make it more clear enough?
2.Lol, number keys are in use for training infantries.
3.What are you planning? Creepy...
1. by group at tower, I mean the units as they spawn can be made to collect at the center tower i.e. they just jun there from castle as soon as spawned instead of running to the current point just in front of the castle. It should be a toggle, as there will be many times you dont want this to happen - obviously when the opponent has the tower for example :)
2. OK, then specific letter keys, or function keys, or shift-number, or control-number etc etc
My point being, when all the units are obscuring each other, it can be impossible to select a specific powerful unit with an ability you need - removing player skill (using the powerful ability to turn the tide, such as poisoning a swarm of swords etc) - and bringing in a random element instead.
3. hehe, yes I am planning for example a simple way to order all sword to charge the back line of healers while all spears attack the giant and the archers focus fire on the magikill - or what ever other orders the player wants to see applied.
Again, I think it would allow for a good implementation of players strategic skill.
And increasing player skill elements, removing frustrating elements of play (like knowing I need poison spray but cant click my mage because he automoved and is obscured by my other units) will add to the pleasure of the players and hence the long term success of the game - in my humble opinion.

1. would be best (IMO) if there was a marker on the screen or mini-map which defalts to the normal gathering point - but by clicking (or combination like shift-click to prevent it getting moved by acident) it can be dragged and dropped at a different location - posibly anywhere on the map, such as at the enemy door-step for automatically bringing up spawning reinforcements in a castle siege.
