Infected used to be able to spam heals non-stop. I got Jackie to put a stop to that. Melee weapons is an effective counter, BUT new players to our servers and members who don't use binds to buy melee weapons ( cough cough ) get absolutely wrecked by chargers spamming heals. That's why there is a 3 second cooldown on SI spamming heals.
But what if you're against a team of stacked survivors? Using conventional attacks ie; flying boomers would get you skeeted easily, the rest of the infected classes are pretty much ineffective since they'll get shot down instantly, unless they co-ordinate in some certain choke points, or buy some heals to dish a little damage if possible.
Sticking to the main question, should we have the SI heal spams back? I would say no, but I'm in favor of reducing the Infected heal timer from 3 to 2 seconds, but have that as an infected upgrade maybe worth "25" points? That would certainly help the infected in some tough games with good survivors, and also a good compromise to some new players and members that don't use a melee weapon.
Doesn't it give you a rewarding feeling when you can incapacitate a survivor by punching them down, crotching them to misery, or boomer scratching them for the lols? All of that with no tank. It's possible with SI heals, lowering it from 3 to 2 seconds? Even better.
