New map idea: Piltover Training Arena

So, I've had an idea for a new map. I'm not sure if this is the right place to post it, but I'll give it a go. The map is called Piltover Training Arena, but the announcer would just say: Welcome to Advanced Training! The map is Summoner's Rift-sized, but contains no lanes, just a 'Jungle' across the whole map, except for the bases on the bottom-left and top-right corners. It would have kind of a steam-punk feel about it. The jungle monsters would be small robotic creatures that grant small buffs when killed. The item set would be the same as the Crystal Scar.

The jungle would consist of various camps, as well as walls, barriers and obstacles. There would be brush in certain places around the map. The centre of the map would be a large pit, Baron-style. Inside it would be a giant robot that can be killed to grant a crucial buff.

Now, the part that sets it further from other maps. There are no turrets, but there are 'Gates' in areas around the map. These gates must be captured. If a team captures a gate, the gate is permanently theirs unless captured by the enemy team. Gates, once capped by one team, cannot be capped by the enemies unless they happen to have the buff from the centre robot. This buff only lasts 30 seconds, and capping takes 15, so everyone has to be quick!

To cap a gate, 2 or more champions have to stand within a certain range of the gate for 15 seconds. Once they start capping, they have to stay in the range or else the cap will reset. Even one champion walking outside the range will reset the cap, unless it is being captured by 3 or more team members. Once an enemy gate is captured by 2 buffed team members, the buff falls off. This means that the 2 team members have to get to a gate within the first 15 seconds of the buff.

I never mentioned the reason they're called gates, did I? The reason is, once a team has 2 gates, they can use one to travel quickly to another (Think of a tunnel.) They have to select the gate, and then it will bring up a short list of other gates available for travel. Each travel puts the entry gate, not the exit gate, out of action for 60 seconds. Locked down gates cannot be traveled from or traveled to.

Once a team has all gates, the enemy Nexus becomes targetable, and able to be killed. Each small jungle camp respawns a minute after defeat, and the large jungle camp (Centre monster is same difficulty as the SR Dragon) respawns 3 minutes after death.

Thoughts?

Edit: Based on suggestions... There are 2 turrets inside each base to keep teamfights in there more fair, SR Nexus style. To cap a gate, the team members must walk inside. Once the team members are inside the range of the gate, they are bound inside the range of the area. More teammates=faster cap+more defense while capping. This is mainly to prevent Tahm/Blitz/Kal/Thresh/Naut/Lee etc trolling. There are 3 gates per side, so a total of 6. This mode makes for good ol' teamfights and objective capping, without the headache of taking turrets to push lane.

2nd edit: So, I realized a mistake I made here. If there are turrets in the bases, then they would be impossible to kill, right? With the 'no minions' thing, and all. So, I thought that maybe, just maybe, that the turrets would have to be scrapped, and instead the teams would be given a power boost (Think Baron buff, but slightly weaker) while inside their own base. Also, each team gets true sight of their whole base, meaning that stealth champions wouldn't be able to hide in there until everyone runs out. I think this would make it a whole lot more fair for the losing team. Also, this would be on a draft pick system to avoid seriously OP wombo combos from coming out as much due to banning.
