Before I answer that, a little preliminary info:
1. Never ward alone (I cannot stress this enough). Ask someone to cover you while you ward.
2. It's okay to ward early! I see some pubs scolding others for placing wards too early. This is just wrong. An early ward means two things - you get to see where your enemy places their ward, and you can easily deward/catch them out of position.
3. Runespot wards are critical until the enemy tier 1 towers have been taken, after which you can move on to more aggressive warding (Radiant/Dire nc).
4. The Radiant ancient ward is arguably the most valuable warding spot in the early game. Try your best to keep vision here. Rune-dependent mids will benefit greatly from this.

Now, to answer your question, the following would be bad scenarios to deward:
1. The enemy ward was just placed and you can't see the warder on the map. This means they might still be in the vicinity and may gank you as you attempt to deward.
2. You just lost a war. Leave dewarding to after winning a war. It can be quickly done while you push.
3. Knowledge of the ward can be used against your enemies. If you know a ward is in the area, you may be able to bait a gank from the enemy.

Thanks for the advise!

Another tip for warding. You can tell where people are warding if you manage to see them. If you see a support appear in your ward vision on your minimap, take a couple of seconds to look at them. You'll know when they place a ward if they look in a certain direction without moving for more than a couple of seconds. And if you see observer wards in the enemy inventory, it doesn't hurt to deward common warding spots anyways.

And please for the love of God, deward before you attempt to Rosh. Or at least smoke up.

Vengeful Spirit is a VERY powerful support who is relevant late game, unlike CM who dies in 3 hits. Compounded by the fact that Vengence Aura has been buffed to a pain in the ass for you enemy. And her awesome ultimate.

Woahh...just play a game and didn't notice they nerfed Tusk snowball skill so badly......LOL

take so long for the charging to execute....my enemy alreaday gone long.....worst still, during charging cannot cancel.....

There is one time when I charge to 1 enemy then suddenly 4 appear from nowhere waiting for me to roll in....hahaha

+1 to this.

Nerf? More like a buff if you ask me. It can now be used to evade spells, and you can save allies too!

We managed to dodge Lion's stun, and even Doom one one occasion IIRC.

Yes, it can be used to evade spells but that changes certainly nerf Tusk combo......usually 1st skill then roll-in and ulti but now this can't be done anymore......and it's very easy for your enemy to escape while you charging the snowball......

So it's more a nerf than a buff to me......

DK 2 : 0 IG .... GG

Double click the skill to instant snowball

People think its nerf cuz dunno how to use it.
its a buff.

hmm just played few game using abaddon , normal build X n Y then basher , scepter then assult , feel like this hero only suitable for support , the dps output is low compare to others carry. ulti with scepter is nice when team battle .

Very good in supports + semi tank .
Been trying play clockwerk few days now , not bad .
GrandElf
You can use the skill twice to speed up the charging .
