Help with Karma "being everywhere"
So I am currently in gold 5, began my LoL career in Silver. I haven't been playing that long, and my main is Karma mid. I have really been focusing on learning the ins and outs (read: counterplays and what not) of Karma and what I need to do differently against each champ I mid against and each comp. One of my issues at the moment seems to be I can't be enough places at once. I'm a utility mage with great burst when I farm....but that is just it...I need to farm. So for instance when I go up against a TF who is constantly TP'ing bot, unless I take Tele, I can never match his map coverage. If I take tele, my kill ability severely suffers given ignite is a great finisher when I just can't complete that last bit of dmg from an Ultimate Q, or kite from ultimate W. I know I have great tools that carry me into the late game by assisting my team (speeding them up, snaring, and constant Q poke), even if I don't scale as hard as some of the other great AP mids, (ziggs, syndra,gragas,etc) but Karma also offers things that those champions do not, and we all know that a team game is much more than "how many kills you get". So I don't focus on that part too much. What I am having trouble specifically dealing with is that in times when Bot or top needs help and I want to help them, my push ability is abysmal and I cannot seem to "make the time" to gank for my team mates as much as I would like because said champions will just clear the lane and disappear. Well If I just follow them , my tower is being be down and it will happen over and over and over. So even if I'm consistently winning trades in lane and killing them, once they force me to my tower multiple times I seem pretty screwed to help anyone else. I rarely out right lose mid(but no one is perfect), but either my bot lane gets destroyed and then I end up with the enemy Bot,jungler and mid taking down my tower, and there isn't much I can do to stop it, so when they do disappear I try to push as hard as possible and take their tower while they destroy bot/top. However, if I'd have had more presence in their lane, perhaps they wouldn't have lost so hard. Granted, I typically expect the jungler to assist in this department, but when you have a pantheon or TF who can tele everywhere, it makes it difficult for me to support them in the early stages like I would like because the enemy jungler will also be involved and its either a constant 2v3 top, or 3v2 bot.
So I guess my question is, are there certain champions you face mid that you take Tele against and forgo ignite? Is there a better build path I can take to maybe sacrifice a bit of my defensive capabilities for myself in order to push better (while making sure I'm not being rekt over and over). Am I just doing it wrong? Feel free to look up my stats and whatnot, I'm not saying I never make mistakes because of course I do. And sometimes I outright lose mid, but sometimes I feel I lost the game for us simply because I couldn't be involved in areas I wanted to be. Thanks for your responses!
