Reg, is most powerfull end gamer if built properly. If you go for a pure passive build with high dmamge output he will tissue paper everything in game (this is a difficult build to make it to end game, But nothing can touch his end game form).
QOT, The shield effect early on is large but weakens over time. Thats a fair trade. Honestly she is one of my favorite for choke point maps. Since her minions are the best DPS minions in game, (shreds Iron Giants late game). Plus the gold bonus helps her late game.
Erebus is only powerfull if you dont know how handle him. First and foremost he has low HP, if you deny him access to your hero early game, Bite is practically an unused skill, making him a rather weak hero that has poor crowd control skills (early on). Just go unclean or Sedna and just capture flags or push other bridges.
Sedna is my favorite, an honestly probably most difficult to defeat, although she does chronically low damamge, she is very fast, and has great life gain potential. honestly depending on what I am goign up against I either go speed or heal. And so far I have yet to run into a challenge. However she still has low DPS, and buying items that boost max hp makes pounce much weaker, and her normal attack is just not enough to be usefull.
TB, is an amusing fellow. people here consider him weak. People here are retarded. My best friend uses him quite eviliy. Frozen form alows him to portal steal (he can freeze the towers, and waltz in). And fire form allows him speed boost for falg control and area of effect attacks which negate generals troops, and kill lots of units.
OAK, is probably my least favorite. granted stilla good general, his abilities always seemed weak, he is terrible general wise,(dropping falgs and then have creature go find you is stupid AI, they should swarm the falgs allowing multiple bridge pushing) always pushing as a n assasin to be effective. And even then he has alot of abilities that are pros and cons the ability to go uber when you die is nice, except for the part that you die. He can be usefull but he does not flow as nicely as other heroes.
Rook, is a tank I have never lost 1v1 as sedna, simply because the rook at best will get one flag. And I will simply take everything else from him. he kills towers pretty good but its easy to counter buy purchasing troops ASAP. He has problems holding multiple bridges and when catapults are built its over. Trick is to make sure you are faster and keep constant pressure. On the flip side, he is strong most people are to dumb to do what I have mentioned and him munching on a towrs to their base is amusing and devestating.
Unclean is quite honestly my nemisis hes not unblanced But he happens to be usfull agianst my two favorite sedna builds. (although quick tower munching rook usually does not encounter problems). He has good versatility but is quite honestly tissue paper. Upgrading your side towers really sets him back alot. Since he has difficulty getting past them. But he is fast.
a big factor people overlook in this game is this. If they can kill you dont fight them. go flag control, or unit kills. If you can beat them bully them. If yoy keep this simple thing in mind, people will rarely get a large upperhand.
