Pushing towers

This is my first post in this forum.I am quite new to Dota2 and I enjoy playing ranged-nuker-support type characters/role , my favourite heroes so far are - Tinker (Rearm+boots of travel - awesomeness), Lina and Husker. Destroying tower really helps in the mid and late games, But you need to gank first and take out the major treat from the opposite team and push for the tower next

Push strat is still the current meta for d2, and still the most competitive way to win matches. However the additional BAN in CM mode has changed that slightly, as it is now easier to ban those 50/50 first round bans like Chen. Which would create a scenario where both teams will be playing a late game farmer.
Team synergy at the end of the day is best = go into a CM match and know what it is you are looking to do (push, turtle/fram, gank), not just think of the best 5 heroes from a pub point of view. like Ursa - great winrate in pub, little to 0 impact in CM..

Teams with really good initiators and teamfighters like tide and sk really help in winning mid to late game. I have seen a tide, sand king, and lycan destroy a team by themselves while barely taking any damage in 10 seconds or so.

Also, try not to screw over your carry's lane while they are farming early game. Destroying a tower too early makes a lane that much more dangerous to farm in.

Thank you for telling me that you two. I now know its important to push tier 1 towers early in the game. Its just that sometimes there is always that team that never pushes or uses teamwork together >__< but yes I understand what you guys are trying to tell me and thanks.

Pushing down towers gets you a lot of gold, as well as map control. To put it in perspective, a Tier 1 tower provides 200 global bounty, a Tier 2 provides 240, and so on if an ally last hits it. If you can push down all of their Tier 1 and Tier 2 towers, and they haven't pushed down any of yours, you've just given each member of your team 1320 free gold, or 6600 total. That's huge. The main problem is, as the game drags on, this gold advantage becomes less and less significant. This is because major tower pushers, such as Leshrac or Shadow Shaman, don't scale exceptionally well late-game. Meanwhile, you're essentially feeding most of your creeps to the enemy team, so their carry can end up quite farmed and wipe your team given enough time.

If your team is not particularly push-oriented, then ganking or teamfighting will also allow you to push down towers because of your flat out hero advantage. In a typical pub, this is what usually happens. Quite simply, ganking/teamfights provide opportunities to push. Pushing provides some gold and map control. And map control, when utilized properly, wins most games.

Destroying towers early, allows for early map control and ganking. Ganking and pushing towers intertwine with each other because usually after a gank, a push happens right after since it's going to be 4v5/etc. your team composition plays a role too, strong early - mid game heroes will dominate in this play. You also get a ton of early gold fairly quick so there's that

If you're pushing hard, you want to force a fight especially if you have strong heroes that dominate early-mid game but still transition pretty well into late like Lycan or Enigma. Lycan and Engima can push pretty hard with their summons, Windrunner is very strong at all stages of the game with powerful pokes and good stun and versatile builds, Earthshaker does well with stopping any engagement and pushes, Sand King does well at destroying the entire team, Chen has global heal, oh-****-button and annoying minions, etc.

that's what I think at least
