Hi I'm Flamebourne. I've been playing Moba for a few years now. I have over 800 games in Hots. I'm gonna cover a few different build idea's I've tested for E.T.C. The Rock Star.

Pros(+)
Mobile
Excellent CC Kit
Alot Of Teamfight Potential
Excellent Substain

Cons (-)
Team Dependant
Mosh Pit Can Be Hard To Land
Often Played To Passive

Sky Temple- Temples are most important aspect on this map. Peel and try and phase the enemy team off the temple circles. If you stand on the circle aswell as a enemy team member does the temple will not shoot. Keep that in mind when trying to contest the enemy for a temple. When temples arn't up try get mercs/boss but always watch the map to know if the enemy team is nearby to try steal the cap. Teamfights are important on this map and losing them at key points (temples/boss) can result in a loss.

Garden of Terror- Seeds take priority on this map. it best to get a big plant Top or Bottom. Faster you pull it and drop it the better chance you get of getting a terror first night. when the terror up and your not in it. Peel for it using your Q or W to keep the enemy away or to miss with the enemy position. If defeding you can use knockback and stun on there terror and that can help you take it out faster.

Blackheart Bay- Coins are the important element here. Your job is to try and assist with kills and peeling for team to survive the teamfights you will encounter. I prefer Mosh Pit for this map getting atleast 1 or 2 enemies in your mosh pit can secure 2 kills. You just roam with the team trying to pick them off pushing them into your team get there coins and win. Mercs are important here because they drop the coins.

Dragon Shire- Shrines=DK. You can go mid and hold the lane so your team can get shrines or you can roam and help secure kills and the shrines. I like to knock them out of the circle. Mercs are more of a distraction on this map then a need. They pressure lanes and assist you with getting the shrines.

Haunted Mines- Skulls are everything a stronger Golem means more push and keeps the enemy team busy killing it. First mine is chaos always. It all team fights and trying to kite. Here you just try peel get some kills and get some skulls. Second mine try focus on landing your skills to peel or secure kills. Mercs don't really do alot of damage but they lane the opposite side of your golem so the seige minions will attack the enemy golem helping kill it aslong as you still got your fort up.

Cursed Hollow- Tributes give enemy a curse which means big push. Each tribute atleast first 3 normally mean teamfights. You try and secure kills and peel for your team. I like to try and push them away so my team can sneak up and steal it. Your mosh pit help in team encounters and can secure kills here. But your Stage Dive can also let you leap right onto a tribute to get it or stop enemy from getting it.

E.T.C is a tank/bruiser. He isn't a assassin or a healer he built to do damage but peel for his team. I don't like seeing a E.T.C running with full health letting his team die. You can Q or W to help your team escape and if you gotta die for them then die. A assassin survives and you dominate the enemy and only you die that's a win. You run and lose all your damage and healers well that not a good exchange. Don't just jump the enemy team but try and assist your team best you can. Q is amazing stun also a excellent escape. W is a nice knockback both for peeling and for pushing enemies into your team. E is a awesome self heal and substains you for poke damage. R depending on which Ult you pick offers certain +/-.
