Yes very good points Bhau.
The Horde appear to have fewer players in general and far fewer in BG's than us Alliance. I don't know this for sure, but it's the impression i get.
For example, i'm starting to get to know the names of the Horde players in BG's more so than the Alliance ones, so i would suggest our player base is far larger.
It has also been said (forget where i read this) that in
general the Horde attract the more mature players whereas us Alliance end up with more annoying Timmies.
What is the consequence of this? The Horde end up with a tight nit, organised pvp player base made up of the mature gamer. That is why, in my opinion, the Horde win more than they lose in BG's.
A few tips for BG's
The best time to get in is from 5pm to 10pm. Weekends are even better for obvious reasons.
Level your character up to the highest it can be for that level group. This means your characters level should allways have a '9' at the end of it, unless it's Eight Zero
There is a good reason for this. If you go into BG's at level 21 for example, you will be facing Horde players with a level potential of 29. This is BAD. Horde already kick arse without us wandering about with 'instagib' written on our heads.
Bring potions, bandages, food and drink and lots of it. Do not go in without it. Use speed potions, they have saved me many times and have also helped me get many kills.
If you're serious about BG's, look up the best pvp talents for your character and spend all your talent points in making your character pvp friendly. If you don't, you'll never be competitive.
Your equipment is important. Have the best you can afford with stats that help pvp play not pve. Often this means stamina will be of more importance. If in doubt, read up on you character to find out.
The little things. These all add up. Sharpen your weapon with sharpening stones. Get powerful enchantments. Add armour kits etc etc. Do EVERYTHING you can to give you and your team the edge.
Look up useful macros and hotkeys and use them. Your abilities should come easily to your fingertips. If you're looking at your keyboard too much or clicking spells and abilities with your mouse you'll end up dead.
STICK TOGETHER. Don't wander about alone.
Eventually i hope that we will be able to field an organised pvp team for BG's. This will be good. When that day arrives we can move onto team tactics. An organised Alliance team is not something the Horde are used to playing against
