SPORTS BASED CHAOS | Blood Bowl - First Impressions 

Nice run down. This is the eighth edition of the game. 4 minutes turns is the chess clock setting. 7s is on a smaller field and with 6 turns per half. It is in the deathzone book but you can find the rules from previous editions online and it was not really changed. One thing to remember about blood bowl is that it is intentionally not balanced. Some teams are just better than others to provide different challenge levels for coaches with different experience levels. Khorne are tricky since they have limited ball handling options and while frenzy is great you can end up having to throw a second block when the dice are against you if you are not careful. Halflings as a stunty team are generally started differently. You want your 2 str 6 treemen and you do not want to spend all your starting gold so that your team value is less than your opponent. This gives you access through the inducement rules to star players and the halfling hotpot(which gives you a chance to steal and use your opponents rerolls). The game can definitely go one sided if you get a numbers advantage but the fast high agility teams (elves and skaven come to mind) can still score touchdowns when they are down players by stringing together not 1s on the dice.

Keep in mind playing halflings without treemen and star players puts you at a huge disadvantage against almost every team. The game has a Tier system each team is categorized into, with 1 being the highest tier and 3 being the lowest. Halflings are tier 3. Still very fun, but difficult to win with!

Chess + Lord of the Rings + NFL

As well as someone had mentioned before there are differences in team value, so if you were playing halflings you probably had access to inducements, and the best inducement for halflings is the master chef which allows you to steal the opposing teams rerolls, which is the one benefit to halflings so you can make them turnover more often

Halfling team without treeman? Also sevens is awesome and much faster!
