And then never do? I had a 
that was going to "come top once I hit my power spike" and then never showed up as the enemy 
farmed and tower dove me over and over and over with impunity.
Baron Barian2 votesHis intention may have been to gank top, but some things can make him change him mind. Maybe another lane offered a more secure kill, maybe the enemy was to strong, maybe you already pushed to deep, a lot can easily happen in a few minutes after making initial plans.
But, looking at that game and seeing how Irellia fed, and surrendered after drestroying 3 towers vs their 1 (seriously, why the fuck did you guys surrender?) I feel like Shy wasn't the reason you lost your game.
In fact, I'm straight up calling your bull shit. You went 2/2/0 vs Ren's 2/3/1, had similar cs. You did not fall behind in the slightest and are just bitching that you didn't have your own personal support in a match-up you were winning against. You are making shit up.

Silly Neeko1 votesKayle: yeah ill gank after my power spike.
Thingamajig1 votesXin lvl 2 with EQ Camille lvl 2 with E+flash shyvanna at lvl 6 with R WW with lvl 6 with R (can earlier if laners are actively trading but not reliable) J4 lvl 2 with EQ etc etc
a jungler powerspike means when their kit becomes usable any time after that is just insecurity
PopcornBunni1 votesSo what about the Shyv not ganking at 6, 7, 8, or 9? It cost us the game since I couldn't get any cs for tank items resulting in us having no frontline in fights later.
Thingamajig1 votesas i said after that is insecurity
AIQ5 votesOther than the fact that you could possibly be losing hard enough that Renek would just 2v1 you two.
Shyvanas power spike depends on few things int's not just 6. First she must have over .85 atkspd to deal decent damage or 2 daggers +. If AD/bruiser. It's generally better when you have chilling smite and know where the enemy is and hit level 7 for the W as it gains very effective damage compared to previous levels and 9 is too far away.
AP Shyvana wants her first jungle item before ganking the spike is huge. She does not want to skirmish until Level 9 + 40% CDR.
So With a Shyvana you have to wait longer but the power spike is bigger than most champions, unfortunately 99% of league players are not nearly patient enough to wait and demand ganks/take her farm. All this does is slow down Shyvana as he Nashors/Boots spike grants her a 4 sec 900 DPS nuke. Which can win games, but who cares about that am I right ? Safe play is for losers.
On a more serious note if you are getting ganked or dove a lot Ward river opening or tri bush. If you are too low to contest go back to T2 and leave th tower to take damage. After being dove once, you are probably in a situation that you can always get dove. Always keep your hp high and never fight or trade soak EXP and gold that you can, never take a CS that is in range of renekton or whoever.
You don't have to win your lane to win the game, you just need to not allow them to carry them game by you becoming useless and him able to 1v4.
Hethalean1 votesWell soem champs have level power spikes (typically 6), but if you have lost so hard by they are 6 that the enemy can 2v1 you, it's a waste of time to put your energy in your losing lanes. Ganking is best on getting your equal or already ahead lanes snowballing fast.
Ganking losing lanes is rarely the best play.
