Overpower goes through shield?

Is again yet another overpowered thing in this game... 20 health on Nexus isn't enough to stop an onslaught despite good spell-play where your spells cost 3 or more and they get constant units battering you. When they change their hand into decimate cards you could lose just by decimate ALONE but with overpower you're not walking the tight-rope you're literally already falling & gasping with the most forceful of lung inhalations to suck the rasor-thin wire back into your mouth before you either impact the ground at full speed or barely get hold of the wire before it rips you a new one!

3 days of relatively good games then 2 or 3 days of constant overpowered garbage that apparently has been around 3 months or more.
I can't believe it needs to be reiterated, but if you need to win early to WIN. Then it's not a balanced game.

Aggro actually isn’t that good in this game. If you’re getting rushed down too much, you could play a frostbite or stun deck to negate early damage.

It seems more likely that you’re not playing a deck that can deal with early aggression. Once you get more cards you’ll be able to build a deck on par with older players.

Just run a control deck, stuff like Heimerdinger and Thresh/Anivia are great at stopping early aggression.

Sweet child, if you are losing to decks running Captain Farron that I fear your play is not as good as you suspect it is--there is sort of a running joke about how bad he is.  But to your point: yes, most LoR games will be decided before Round 10--especially if neither side is running healing.  I personally would consider Rounds 6-9 to be "midrange", not "early", but that's semantics.  As others have pointed out, there are probably deck improvements that would either help you apply more early pressure or better control aggro opponents--perhaps you'd like to share your current deck?

Captain FarronBADCARDNAME is designed to teach new players the concept of finisher cards.

Farron is easy enough to fit in any deck as a stand alone win condition. Replacing the hand with Decimate is a very powerfull effect indeed.
It will put pressure on the opponent to win the game in the next few turns or be overwhelmed with direct damage.
This "preassure" is also know as Win condition / Boss card / Finisher. 

Farron is strong but isn't overpower at all.
First, Decimate costs 5 mana. While it puts preassure, it will take multiple turns to play all Decimates.
Second, the hand will be filled but nothing then Decimates. That means the player is now commited and won't be able to react to anything on the board.
Third, Decimate has SLOW spell speed. In tight situations, when both players nexus are low, the speed matters a lot. And those spots happens very often.

Conclusion: Captain FarronBADCARDNAME is just an introduction to finishers. Easy to play, doesn't require other cards to work and can fit in almost any deck. The downside being the slowest one to close games when compared with all other finishers.

Edit: The video above posted by OldManSanns illustrates everything stated in my post. Worth a watch.

Complains about aggro. Aggro style isnt the strongest type in LoR. 

Aggro is dominant in HS. Ironic
