Okay, so about jihading. Frankly it's a good tactic if you've A) got nothing better to do with those lovely RDX packs, or B) you're pissed at the armor whore destroying half of your team. If it scores you kills, you survive, and you don't injure teammates, it's a tactic that works, and very effectively sometimes. I admit, jihad is not one of my primary, or even secondary strategies (more like tertiary), and people frown upon it...because not only does it work a lot if you're good, people accuse you of being noob. Admins ban people who do excessive Jihad because they're pissed they can't find a counter-strategy; I suggest you freaking n00b admins, that if you see a truck loaded with explosives barreling towards you, either blow him up before he can get close, or abandon your vehicle. Instead of being an ass and bitching about a tactic that, while cheap, is still plain old effective. NOTE: transport gunship ramming is entirely a different story. That's not only cheap, but a low blow...especially when ramming walkers, which have an extremely long respawn time on most maps.
Bottom line: use jihading only if the enemy has armor ripping half your team apart, and the only way to get close is with one of the jeeps loaded with explosives. Take one for the team if you think it'll help them win.
