most overrated things in DotA

I voted for MoM. I get that you want extra attack speed and lifesteal does help your survivability for a bit, but what are you gonna do when you get stunned in the face? They pick it on incredibly squishy heroes too. I understand Faceless Void since he can survive with a well-placed Chronosphere and a well-timed Time Walk in addition to his Backtrack but I would rather avoid the item on squishy heroes altogether.

This might sound noobish but I kind of want to say magic wand. I mean I can see it being really useful if your laneing against bristleback or batrider because of their (usually)constant ability spamming but most of the time I'll notice both enemies and my lane buddy have one and none of them have many charges. But maybe everyone's seeing something I don't because everyone has them and most guides suggest them.

Cheap stats, great heal, you can fix some heroes' mana problems with pt switching and wand. That is mostly why I think people do it. It really does pay-off for the little investment that it is.

i really feel like riki's invis is not over rated that much and no i do not play riki he can use items and spells while invis so you can lets say get a dagon 5 and use that over and over again while invis you just cant do that with ANY other invis source i feel as if they should nerf riki by removing that "feature" and just make him go visible again it would really help divercify low level pubs:)

I don't think so, their are very few instant heal's in the game, and at full charge it usually provides enough mana to pop that one more spell when you need it.
Plenty of times where teamfights have been swayed because I wanded up enough mana to get off another stun or Mekansm, or barely survived a chase as they thought that final projectile would finish me off.
If anything its underrated, its a fairly uncommon item in the level of matchmaking I'm in.

Mask of Madness on almost every hero people build it on, and the funnier part is when they just stack damage items on top of it and wonder why they keep dying. Saw a mask of madness Slardar sprint into a fight, way to die bud! What's with people with MoM on heroes like drow and sniper? They take 3 hits to kill without the mask on, with it they just die. I still say Void and Abbaddon are really the only two I can see running around with it. Void situationally, and Abaddon going carry? Screw it he's got borrowed time anyway

i anctually understand it on sniper. he already is a trash hero that dies if he gets caught, why not make increase your dps with this quite cost efficient item? does it really matter if you die in 4 or 2 seconds?

I think Sven is another Hero that benefits from the Mask of Madness, after a Black King Bar and probably an Armlet of Mordiggian: as his movement and attack speed aren't that great (understandable as he's a STR Hero) and kiting is a big issue for him, the extra speed and lifesteal, especially since Warcry gives you extra armor, are really handy if you have a setup like Black Hole or Static Storm. I find it quite decent on Abaddon too, but I don't really like it on Faceless Void; I think it's just me. Still, as Void can farm really fast, most of the time a Drum of Endurance or a Maelstrom are safer options in my opinion because your teammates should be helping you with AoE/teamfight spells. If you just want to solo everyone, take your time to farm and go Battle Fury + Mjollnir. I'd only take MoM on him if I needed to put very early pressure in teamfights.

Also, the Magic Wand is a fantastic item: bust mana or heal can make the difference between life and death or give you enough mana to cast an extra nuke and kill the fleeing enemy. It's very cost-efficient, made from cheap items and a no-brainer for supports.

yep. sven and void are really the only 2 heroes i can under stand a MoM on. Sven for exactly the reasons Peppo said + if you are having a Black King Bar + Deadalus you can rek faces damn hard .... 1.5k cleave crits with 2.0 attacks per second is something you really never want to be close to. As for void i think its pretty nice if you want to be "useful" in the earlier stages of the game. With a Mask of Madness and a single Javelin you can actually kill A LOT of solo heroes.

On sniper it really is a dangerous pickup. If the enemy team hasnt any gap-closing abilities and you are really confident in your positioning however, a MoM'd Sniper can be pretty damn hard to deal with.

It isn't just you, you need to be RNJesus to make Backtrack work well enough to justify it
