First off, I want to say I am very excited and probably going to sound green. Though, that is what I am. I was looking into other mini wargames, that shall remain nameless, but I found that they are very expensive and not very 'New player oriented'. So I did a search for alternative games and found warmahordes. After watching a few battle reports, I was hooked. So I got my friend to go into buying an old menoth vs khador two player battle box. I have a few random questions that I haven't been able to find.
1. I know this box I bought is mk2 and the cards that come in the box are probably out of date. To replace them I probably have only two options: 1. Buy a faction deck. 2. Buy a deck on the war room 2 app. Now, my question is: in the card errata portion of the official website there are PDFs with new cards in there, If a card does NOT exist in there does that mean the old card is still valid?
2. Can I take part in battle-box battles with models from this mk2 box?
3. I actually make some money for painting commissioned portraits of people's pets and have decent acrylic paints already. I understand that one of the reasons for buying faction paints is to maintain the exact hue of each color, but I am pretty good at mixing paints. Does anyone have any tips or links to resources with good information on how to successfully paint my models like this?
4. This next question is related to game play, everything seems to be in the rule book, but I wasn't sure about this one thing: does focus regenerate or do I have steal it back from my warjacks?
Thanks for reading and sorry for the wall of text.
TL;DR: I am new and exicted. I have questions about mk2 model cards, painting, an focus points. Questions are in bold.
