Twins buffs and nerfs

It's pretty apparent the only power behind The Twins is Victor. You might as well just call Victor the killer, and Charlotte the hooker (no pun/Samination reference intended). I think these changes would make the killer more balanced and fun:

• Remove the cooldown penalty for Victor successfully downing a survivor. It's stupid that you can use your power effectively and still get punished. Victor should only be crushable on missed attacks or while idle.
• Accordingly, Victor's regrowth time should be increased from six seconds to at least 15. It should feel a lot more rewarding to crush Victor than it is now. Six seconds is hardly any time to wait to reuse Victor. Imagine if Ghost Face could reenter Night Shroud in 10 seconds, would that be fair? Similar idea.
• Lastly, increase Charlotte's movement speed by 2% when Victor is detached. As it is right now, Charlotte is nothing but a M1 killer. That is boring and dull. This would provide a little more benefit to leaving Victor idle, and also make sense (as she is not carrying his weight, even if he is of small stature).
