In other words, your experience with necro and windy is limited to dueling one person who probalby isn't even that good. I however have dueled most of the top necs and windies on west and some of the best on east.I have used both, on and off battle.net. I dueled my friend with both a top-notch necro and a top-notch windy, and I beat his necro and windy with both. That's what I said. But from my experiences, a Windy eventually ODES have the upper hand, just that beating the necro is annoying. Theo nly quick way to do it that I found was delayed namelocking.
As for the necro vs. his Windy, either he sucked or then I just did too good on the Necro, as I had a better record on beating him with a necro than beating his necro with a druid. But yes, both could beat both. And yes, a Bonemancer does have trouble due to summon stacking. And yes, a good windy won't be stupid enough to go too offensive.
So, what do you actually do without Widow or Fort? teleport to the blindspot and zerk? However, I've realized that most hammerdins nowadays are desynching ones, which can easily be beaten without fortitude or Widowmaker.
Most hammerdins these days realize that they are not invincible by casting hammers in the same spot, so blind spot telezerk will not work most of the time. . against desynchers,I usually do desynch long ww to cut off them off or do tele wws to cut them off. there's a lot of anicipation and luck involved. Also when they are really low on health and start playing defensive you can unsummon lock tele ww them when u think they are charging away(not casting hammers). Yes it's very risky and you could end up dying instantly but if you time it right it works most of the time. I'm not very skilled at dueling tele hammerdins but most of them aren't that bad. Bvcs like blobs and xe-malice found ways to kill tele hammerdins without even getting hit once.
