I do Shotokan (Karate) and Judo, Shotokan for much longer.
You are deluded if you think any amount of training is going to help against multiple attackers.mitchell271 said:If you're trying to choose a martial art I might be able to help.
Karate: fighting off multiple attackers quickly and efficiently; medium amount of counters in counters; large emphasis on pattern memorization and strength
Tai-kwon-do: fighting off 1-3 attackers quickly and precisely; lots of counters and variations of kicks; large emphasis on precision strength
Judo: fighting off few attackers; lots of counters; large emphasis on throws
Muay Thai: fighting 1 attacker at once; few counters (i think); large emphasis on using brutal strikes with elbows and knees to quickly subdue an opponent
